Hmm, I'm skeptical that it was a cultural issue. I went to a suburban high school and the issue wasn't that we didn't somehow know about the top schools, it's that you had virtually zero chance of getting in.

My best friends were the top couple students from my year and the year before me and I watched them mortified as the pattern played out -- they each applied to several top tier universities and were deflated when the stream of rejections came in (though one got into Notre Dame). Just being a valedictorian, active, national merit scholar wasn't enough. Most ended up going to their "safety" schools -- either University of Texas or Texas A&M.

My takeaway from that was that if you were white, middle class and middle-American suburban, that there was almost nothing you could do distinguish yourself enough to get into the country's top schools. As such, I think this announcement is more meaningful for folks from genuinely poor backgrounds than for those from relative suburban privilege.
