The biggest Price Gougers in America

I have recently signed up to go back to college for the first time in more than a decade. Holy cow!!! I hear people complaining about the price of oil, but what about the American college system? The cost of schooling goes up by double digits every year, and there is no investigation about price gouging or profiteering? If anything else, food, clothing, anything other than taxes would go up like tuition has year after year, the federal government would hold televised hearings, to show that they are "doing something." How come these terms that apply to the public, such as usury, price gouging, profiteering, racketeering, etc. do not apply to the federal or state government? Just wondering.
