I'd be ecstatic to see colleges put a stop to that as well.
We must be talking about state colleges and not private colleges.
A private college could elect to allow the children of hindu elephant herders to be preferred if they so wish. They are PRIVATE!!
A publicly funded college, on the other hand, must permit ANY taxpayer to have equal access. If they get my money, then I should have some chance of attending. The best way to do it is probably by lottery of ALL who are fully qualified. (Notice that I didn't say BEST qualified.)
They can enable the BEST QUALIFIED to jump the lottery by providing them scholarships for academics, music, sports, whatever.
Then put the rest in a hat and draw names. Can't get more fair than that.
