OPINION
CLIFTON, Circuit Judge:
Rafael Castro-Martinez ("Castro"), a native and citizen of Mexico, timely petitions this court for review of a decision of the Board of Immigration Appeals affirming an immigration judge's denial of his applications for asylum, withholding of removal, and relief under the Convention Against Torture. We conclude that substantial evidence supported the BIA's conclusion that Castro failed to demonstrate past persecution or a well-founded fear of future persecution on account of his homosexuality or HIV-positive status. The sexual abuse Castro suffered was not inflicted by government actors, and the BIA had sufficient basis to conclude that Castro failed to show that the government was unable or unwilling to control his attackers. Accordingly, we deny the petition.

I. Background
Rafael Castro-Martinez entered the United States without inspection in 1995. He subsequently resided in California. Castro, who is homosexual, believes that during his time in this country he contracted HIV. He found out he is HIV-positive in June 2004.
In 2007, Castro returned to Mexico for two weeks to visit his mother. He sought to reenter the United States at San Ysidro, where he turned himself in to immigration authorities and requested asylum. He was *1106 issued a Notice to Appear and charged with removability for entering the United States without valid travel documents. He conceded removability in a hearing before the immigration judge. He filed applications for asylum, withholding of removal, and protection under the Convention Against Torture, claiming that he had experienced past persecution in Mexico as a homosexual male and that if removed to Mexico he would face persecution and torture on account of his homosexuality and his HIV-positive status.
Castro's claim of past persecution was based on sexual abuse he experienced as a child. In testimony that the immigration judge found credible, Castro testified that he had been teased and harassed for being gay since he was very young. When he was between six and ten years old, he was raped brutally and repeatedly by two male teenagers. Castro believed he was victimized because of his homosexuality and feminine characteristics. He never told his parents about the abuse, because his abusers threatened that they would beat him and kill his parents if he told them. Castro asserted that given these threats, and the stigma associated with homosexuality in Mexico, it would have been unreasonably dangerous for him to have reported the sexual abuse to his teachers, neighbors, or parents. Moreover, he claimed that because the Mexican police are corrupt and ineffective in dealing with crimes against homosexuals, it was unlikely that reporting would have brought an effective response or protection from the state. Castro contended that the Mexican government was unwilling and unable to protect him from the sexual abuse and that this constituted past persecution on account of his sexual orientation. Castro argued that this past persecution established a well-founded fear of future persecution under 8 U.S.C. § 1101(a)(42)(A).
Castro argued further that even if he was not held to have suffered from past persecution, he nonetheless qualified for asylum based on having a well-founded fear of future persecution in Mexico, where the government systematically harms gay men. He testified that if he now returned to Mexico he feared that he would be beaten, tortured or killed for his sexual orientation. To support his fear, Castro submitted country reports documenting societal discrimination against homosexuals in Mexico and attacks on gay men committed by private parties. He also presented evidence of widespread police corruption in Mexico and incidents of police violence against homosexuals. Castro also claimed to have a well-founded fear of future persecution on account of his HIV-positive status. He testified that he believes HIV medication is not available for gays in Mexico due to discrimination against homosexuals and that he will die "in a slow and torturous way for not having the medication that I need."
The immigration judge found Castro removable and denied his applications for asylum, withholding of removal, and protection under the Convention Against Torture. The IJ concluded that Castro failed to establish eligibility for asylum because he did not demonstrate past persecution or the likelihood of future persecution at the hands of the government or groups the government was unwilling or unable to control. See Sangha v. INS, 103 F.3d 1482, 1487 (9th Cir.1997). The IJ found that Castro had not presented any evidence that the government systematically harms gay men or that it is unwilling to control those who would commit violence against homosexuals. The IJ pointed to country reports in the record indicating that Mexican law prohibits discrimination on the basis of sexual orientation and that the Mexican government has made successful *1107 efforts to promote tolerance of homosexuals.
The BIA dismissed Castro's appeal. The Board concluded that Castro had failed to establish eligibility for asylum because he had not shown that the Mexican government had been unwilling or unable to protect him from his abusers, or that homosexuals and HIV-positive individuals are subjected to officially-sanctioned discrimination in Mexico. The Board noted that Castro did not report the sexual abuse to the authorities and that he failed to provide a compelling reason as to why seeking state protection would have been futile. See Ornelas-Chavez v. Gonzales, 458 F.3d 1052, 1057-58 (9th Cir. 2006). The Board further concluded that Castro had not demonstrated that he would be unable to secure treatment for HIV in Mexico, or that lack of access to HIV treatment was a problem experienced only by homosexuals. Since Castro failed to meet his burden of proof for asylum, he also failed to establish his eligibility for withholding of removal. The Board also denied his CAT claim, holding that Castro did not demonstrate that it was more likely than not that he would be tortured in Mexico.

II. Discussion
We review the BIA's construction and application of the law de novo. See Murillo-Espinoza v. INS, 261 F.3d 771, 773 (9th Cir.2001). We must uphold the BIA's factual findings if supported by "reasonable, substantial, and probative evidence on the record." INS v. Elias-Zacarias, 502 U.S. 478, 481, 112 S.Ct. 812, 117 L.Ed.2d 38 (1992). Our review is "confined to the BIA's decision and the bases upon which the BIA relied." Navas v. INS, 217 F.3d 646, 658 n. 16 (9th Cir.2000).

A. Past persecution
To be eligible for asylum, an alien must demonstrate that he is unable or unwilling to return to his home country because of persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or a political opinion. 8 U.S.C. § 1101(a)(42)(A). Homosexual men in Mexico can constitute a social group for the purpose of an asylum claim. See Boer-Sedano v. Gonzales, 418 F.3d 1082, 1087-89 (9th Cir.2005). Persecution is the "infliction of suffering or harm . . . in a way regarded as offensive" on the basis of one of the protected grounds. Prasad v. INS, 47 F.3d 336, 339 (9th Cir. 1995). To qualify as persecution for the purpose of asylum, an act must be inflicted either by the government or by individuals or groups the government is unable or unwilling to control. Sangha, 103 F.3d at 1487. Violence or discrimination inflicted by private parties does not constitute persecution if it is not condoned by the state and if the state takes reasonable steps to prevent and respond to it. See Gomes v. Gonzales, 429 F.3d 1264, 1267 (9th Cir. 2005); Ghaly v. INS, 58 F.3d 1425, 1431 (9th Cir.1995).
Substantial evidence supported the BIA's conclusion that Castro had not been the victim of past persecution as defined under the law. Although horrendous, the sexual abuse Castro experienced was not inflicted by government actors. Castro acknowledged that he had never been subjected to violence by government officials in Mexico.
Likewise, evidence supported the conclusion that Castro failed to demonstrate that the government was unable or unwilling to control his attackers. Castro testified that he never reported the abuse to the authorities. In determining whether the government was unable or unwilling to control violence committed by private parties, the BIA may consider whether the victim reported the attacks to the police. *1108 See Baballah v. Ashcroft, 367 F.3d 1067, 1078 (9th Cir.2004).
To be clear, "[t]he reporting of private persecution to the authorities is not. . . an essential requirement for establishing government unwillingness or inability to control attackers."[1]Rahimzadeh v. Holder, 613 F.3d 916, 921 (9th Cir.2010). An applicant can demonstrate the government's unwillingness to respond to violence by "establishing that private persecution of a particular sort is widespread and well-known but not controlled by the government" or "showing that others have made reports of similar incidents to no avail." Id. at 922. In other words, the applicant need not have reported the crime if he can demonstrate that doing so would have been futile, or that contacting the authorities would have subjected him to further abuse. Ornelas-Chavez, 458 F.3d at 1057-8.
In this case, however, substantial evidence supported the BIA's conclusion that Castro failed to sufficiently explain why reporting the sexual abuse to the authorities would have been futile or would have put him at risk of harm. Castro's reasons for not contacting the authorities were similar to those offered by the petitioner in Castro-Perez v. Gonzales, 409 F.3d 1069, 1072 (9th Cir.2005), in which we denied the petition of a young Honduran woman who was raped twice by her boyfriend. Castro-Perez did not report her boyfriend's assaults to the police because she believed they would not investigate a date rape. Id. We determined that this explanation was insufficient, given that there are criminal laws against rape in Honduras, and Castro-Perez had not shown that these laws were not enforced.[2]Id. Castro-Perez failed to demonstrate that the government must "bear some responsibility for [her] rapes because it is either unable or unwilling to control rape." Id.
Here, it was not unreasonable for the BIA to perceive Castro's explanation for not contacting the authorities to be less than persuasive. Castro argued that he could not report the sexual abuse because of threats from his attackers. While private threats may explain why an asylum applicant did not report the crime, "the question in an asylum case is whether the [authorities] could and would provide protection." Rahimzadeh, 613 F.3d at 923. As the BIA observed, there was no evidence in the record that Mexican authorities would have ignored the rape of a child, which is a crime under Mexican law.
Castro also claimed that he was afraid of contacting the police because they would likely abuse him on account of his homosexuality. Castro presented country reports documenting police corruption and participation in torture, abuse, and trafficking, as well as incidents of police harassment of gay men. But the record *1109 did not compel the conclusion that the police would have disregarded Castro or harmed him if he reported the attacks. At the time of the abuse, he was a young child. In addition, the BIA noted country reports in the record indicating the Mexican government's efforts to prevent violence and discrimination against homosexuals, which have increased in recent years. Mexican law prohibits several types of discrimination, including bias based on sexuality, and it requires federal agencies to promote tolerance. In April 2005, the Mexican government launched a radio campaign to fight homophobia in conjunction with Conasida, the National Center to Prevent and Control HIV/AIDS. Country reports submitted by Castro noted the ongoing improvement of police treatment of gay men and efforts to prosecute homophobic crimes.
In sum, while we do not diminish the trauma Castro experienced, substantial evidence supported the BIA's conclusion that Castro's failure to report the crime undermined his claim that he was unable to seek protection from the state against his abusers. See Ornelas-Chavez, 458 F.3d at 1057; Rahimzadeh, 613 F.3d at 920-23. Because Castro did not meet his burden to show that the government was unable or unwilling to control his attackers, he failed to demonstrate that he had been the victim of past persecution.

B. Fear of future persecution
Substantial evidence also supported the BIA's conclusion that Castro failed to demonstrate a well-founded fear of future persecution. To establish a well-founded fear of future persecution, an applicant must show that he has suffered persecution in the past, or the existence of a "pattern or practice" of persecution against similarly situated individuals who are members of a protected group. See Knezevic v. Ashcroft, 367 F.3d 1206, 1213 (9th Cir.2004). A "pattern or practice" refers to "systematic" persecution. See Wakkary v. Holder, 558 F.3d 1049, 1061 (9th Cir.2009); Bromfield v. Mukasey, 543 F.3d 1071, 1078 (9th Cir.2008). Citing evidence of societal discrimination against gays in Mexico, and attacks on gay men committed both by private parties and the police, Castro argued that the Mexican government systematically harms gay men and fails to protect them from violence. The record did not compel this conclusion, particularly in light of the country reports indicating official efforts to prevent violence and discrimination against homosexuals.
Castro also claimed to have a well-founded fear of persecution insofar as he will be unable to receive HIV treatment in Mexico because he is homosexual. Castro testified that "homosexual men are not a priority to receive medication" in Mexico. Substantial evidence supported the BIA's conclusion that, based on the documentary evidence provided by Castro, lack of access to HIV drugs is a problem suffered not only by homosexuals but by the Mexican population as a whole. The record noted the high cost of HIV drugs, lack of access to health insurance for the poor and unemployed, and possible government mismanagement of funds allocated for HIV treatment. "Generalized economic disadvantage" does not rise to the level of persecution. Raass v. INS, 692 F.2d 596 (9th Cir.1982). The BIA was justified in concluding that Castro failed to demonstrate that he would be deprived of treatment for HIV in Mexico because of his membership in a protected social group.

III. Conclusion
Substantial evidence supported the BIA's conclusion that Castro did not demonstrate that the Mexican government was unwilling or unable to control his attackers, and that he therefore failed to establish *1110 eligibility for asylum. Because Castro did not demonstrate eligibility for asylum, his claim for withholding of removal, governed by a more stringent standard, is also foreclosed. Gomes, 429 F.3d at 1266. In his opening brief, Castro did not challenge the BIA's denial of his CAT claim and therefore waived it. Arpin v. Santa Clara Valley Transp. Agency, 261 F.3d 912, 919 (9th Cir.2001). Accordingly, we deny the petition for review.
PETITION DENIED.
NOTES
[*]  The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R.App. P. 34(a)(2).
[1]  Contrary to what Castro argues, the BIA did not impose a "reporting requirement" but regarded Castro's failure to report the abuse as one factor in its assessment of the Mexican government's willingness or ability to control his attackers. The BIA concluded that on the record as a whole, Castro had "not demonstrated that the Mexican government was unable or unwilling to protect him from harm."
[2]  By contrast, we have held that the fear of reporting is not speculative when the victim had been subjected to past abuse by the same parties and previous attempts at reporting were futile. See Boer-Sedano, 418 F.3d. at 1088 (victim's failure to report sexual assault by police officer was reasonable when he had been assaulted by the same officer in the past without intervention from other officials); Ornelas-Chavez, 458 F.3d at 1058 (failure to report sexual assault to the authorities was reasonable when extreme violence and indifference characterized the victim's previous dealings with government officials and police had abused him in the past).
