Except that such goods are increasingly not priced via the market.
If you're smart enough to get into an elite university, you don't have to worry about the cost. Full stop.
That being said, I do think we have a societal responsibility to set things up so that this applies across the board. Personally, I think income inequality is fine and maybe even good if we can also have:
1) Basic income, so that even if your parents aren't wealthy you still have all the necessities.
2) Well-funded and high quality public education (from pre-K up through college)
Personally, I actually think income inequality can make these things easier to achieve for 2 reasons:
1. Each individual dollar matters a lot less to billionaires, so they're a lot more willing to give away a huge percentage of their wealth. This trend is very evident with tech billionaires. If Warren Buffet had his wealth spread amongst millions of families, would each one be willing to give up 90% of that wealth?
2. The winnowing of the middle makes redistribution more palatable. A large part of current politics is moderately well-off people feeling morally superior to slightly less well-off people. If society becomes more bimodal, it's a lot more possible to pass aggressive redistribution policies.
