Are coaches paid too much?

Do we as a nation invest too much in collegiate sports? The ncaa makes a ridiculous amount of money every year and it is either distributed via salaries, equipment, or other expenses.

Could we find a way to distribute revenue in order to help fund more opportunities within our schools?

I find it crazy how the average tuition for a University in Germany, for example, is about 500 euros per semester, while ours in the United States is well over thousands per semester. That is not including books, housing, or food.
