I agree with people with more paying more into the general fund of the government. But when major parts of the US budget get deficit funded, why does higher education get individually loaded cost wise? It makes no sense, there's no real need to discourage people from getting too much education. And long term loans, are just as inflationary to issue to the economy - and when you collect the interest back long term, you're just causing a drag on economic expansion.
I completely agree with you that this approach to education isn't ideal and that we collectively would be better off if the onus for funding education was shifted back to the general tax payer again. That said, if you have a system in which the education dollars are limits, like we currently do, the best approach in my opinion is to charge people based on their ability to pay.
