My parents were really supportive of me in school; someone whose parents weren't as supportive of them, who got the same grades as me is probably a better student and will be more sucessful with a given set of resources than I would since they overcame more adversity than I did.

It's a little crude to use race maybe, but it probably isn't a terrible approximation. What would be great is if people had to disclose any paid preparation for the SAT or the hours their parents spent with them growing up but that's probably a long way off.

Overall, this issue is framed to be as controversial as possible by political interests but it really isn't that big a deal.
