Great find. You missed the best part: <<Families with incomes between $75,000 and $150,000 will contribute from 0-10% of their income...>>

That means for income <= 75K, Harvard tuition is free! That is impressive. Their system looks fair in comparison to other US universities. This system looks similar to progressive taxation (higher income pays more taxes).

For readers not familiar with US university system: This will not include "room & board" (housing & food).
