First off, not everyone with a college degree ends up with a huge amount of debt. Many even manage to go to elite schools and end up with little, or no, debt. Those who are academically gifted usually has scholarships that pay for most, or all, of their college education.
And even for those who aren't true scholars, the cost should be significantly below $140k. If you aren't good enough to get a full (or nearly full) scholarship, DON'T GO TO AN EXPENSIVE PRIVATE SCHOOL. Start at a community college (still very cheap), then go to a state school, get whatever scholarships you can, work during the school year and over the summer, and end up with a far more manageable debt load- probably well under $30k.
Some of you folks make it sound like every kid who goes to college ends up with $130k in debt, a degree in women's studies (or something equally useless) and a job at Walmart. I assure you, there are plenty, even today, who graduate with useful degrees, get good jobs, and have very manageable debt (or no debt at all).
