Wait.  When there is more demand for any given product or service, does not the price go up?  When hundreds of thousands of people attend our colleges when they shouldn't even be here in the first place, how does the law of supply & demand suddenly stop working in this scenario?  The more demand for college, the more they're inclined to raise tuition rates.  When tuition rates rise, certain segments of the native-born population stop attending.  Too complicated?  I hope not.

Deport them.
