Or those colleges could figure out a way to cut costs and stay in business. Plus, what NCT said is true, too. It's getting to the point that unless someone is going to make six figures, college is a horrible investment. And I don't buy that broadening ones perspective as something only college can provide; simply reading good books can broaden ones perspective - don't need a college degree to do that.
Unfortunately, the "They'll figure it out" method won't work in this case.
An organization can't survive an overnight reduction in revenue like this would cause.
In order to run a college, one must have highly trained faculty to represent all of the areas of the curriculum. Additionally, the college must have sufficient supporting staff, security, etc. to function. Also, the college has the expenses related to facilities and upkeep.

In an economy with high unemployment, having only a high school education is not going to make you very competitive.
