Should they also cut their kidneys out and sell those too?
For someone not in your system, the expectations that seem normal to you sound absolutely insane to others.
Nobody is forcing them to pay this price any more than you are forced to sell a kidney for a private jet.
Education costs are out of control, but you can still get a degree elsewhere for 10% the MIT cost, and have it paid for entirely by the government if you are low income
Does MIT include the market value of their kidneys in their assessment? You might have lost track of what is being discussed here.
Anyway no, they should not cut their kidneys out and sell them.
