a) you've failed to parse the prose you quote and think that it's complaining outright about universities allowing in applicants from "disadvantaged backgrounds", when in fact it is complaining about allowing in applicants specifically because they are from disadvantaged backgrounds who would not meet previous merit-based admissions criteria, or
b) you genuinely mean to imply that advocating for the ideal of meritocracy is not merely flawed but somehow equivalent to supporting a policy of explicit racial segregation and class-based admissions, or
c) something else entirely
I'm downvoting, primarily because the ambiguity about what you're trying to say makes this comment impossible to substantively engage with.
