Most Americans can't afford that much education because they are caught up with materialism and are saddled with taxes (either directly or on the goods they buy or the companies that make them).
So now American higher educational institutions are only able to maintain their "high standards" with the money that is more and more going to be available from outside of the country.
At least some Americans can afford it.
I mean - when you put that much of a country's money into stuff like the military,or the interest on US' massive debt - how much of the money can come from within for things like education?
