There are a couple independent schools around the country that use a sliding scale tuition program. Every family is charged a different tuition level based on their family income and assets and siblings. It is intended to eliminate the distinction between financial aid and full paying families and encourage more "middle class" families to consider independent schools. It also is designed to eliminate the tuition gap and the annual fundraising needed to fill the typical independent school's budget, though they still do lots of capital campaigns. These schools also set a maximum tuition cap so extremely wealthy families don't get charged $100k.
Here's an example of one such school

Any DC area schools considering such an approach? As parents, what would you think of this kind of tuition model? Would you find it more or less attractive when considering schools?
