Harvard’s assumption that the parents can shill out tens of thousands for their kid is just dumb. They don’t realistically take into account parents that don’t care much about education, large families, parents with lots of debt, etc.
That said, yes, if you have more money left over per child than someone else, you are expected to pay more.
I also asked a specific question, which you completely skipped, while doubling down on a fairness argument that this thread wasn't even about. You act knowledgeable in the matter and then aren't able to dive in, only defend your position. Its fine to say "I don't know", but right now what are you doing?
Were you saying that Harvard's "affordability" was anywhere close to the $3,000 tuition / semester I ended up paying? And that's because Harvard routinely makes up any number based on a variety of financial variables (which aren't as simple as "income") and ultimately feelings?
Household income of parents is obviously a bit of weird proxy for an almost-adult child. But, I bet it works quite well at finding academically inclined people who assumed they couldn't afford X University and persuading them that they can.
The alternative would probably be something like requiring all parents to buy "education insurance" for their children, which turns into a lump sum at 18, and then giving people with lower incomes a discount on that insurance. (This is a terrible idea, don't do it. Make education cheap or free instead.)
I'm not arguing that Harvard isn't expensive for affluent families, but even with an income like that you would still probably get financial aid. Harvard doesn't charge anything like full tuition to families under $200k a year, the point is just that they charge nothing at all if you make under $65k.
I fail to see how that is unfair.
