Because that was me, just some regular lower class guy who had good grades and a not particularly unique angle. It used to bother me a lot that somehow these other people were "better" than me but I realized not too long ago that in reality, these schools are simply not meant for people like me but instead they are for the elites.
In retrospect, I wish I had spent more time learning about and pursuing the high ranking "techy" type schools like MIT/UMich/Caltech/Cal and less time chasing after these "prestigious" ivies. Plus, out of my generation of cousins (n=30+) only 5 went to an Ivy League school or equivalent and 2 of them went to the same high school as Bill Gates and the other 3 were sports recruits. Anecdotal of course but even amongst my high school class the only people who went to an Ivy league had 1) Ivy league professors as parents or 2) multi-millionaire levels of wealth.
