If you go to an in-state community college and then matriculate to an in-state university in my state the total cost of college is (~$4500 for 2 years of CC living at home + ~$25000 for 2 years of closest to home in-state school) ~$30000 + the cost of living at home.
Meanwhile people continue to whine about sending their kids to school in places where they wrack up that much in debt per academic year before accounting for housing and travel expenses.
If you don't want to be in debt and you aren't rich or dirt poor make reasonable decisions and stop whining. If you can afford to replace your mini-van with a Prius, you can probably afford to send your child to college, especially if you save the difference during the CC years.
The real issue is that people feel entitled to the best schools and will so make absurd decisions to enable it regardless of what their child is studying or how well they actually do in college.
And all of the above said, I do agree that college is increasing in price more than it should. I think it's because research and lifestyle costs are getting pushed into tuition combined with state legislatures who don't want to support colleges in their state budgets that are really doing it. This has many pernicious effects, like transforming the college meal plan into a clone of your closest mall's food court.
