And I'm not rich. And I have a fourth kid in high school. I do get some decent financial aid, so I end up paying about $20-25k a year for each kid.
What I see happening starting in 2013 is my oldest graduates and comes back to live with us while she tries to find a decent job with about a 3.0 gpa as a history major. Her brother will be in a similar boat two years later. And so on.
This is my advice for those with young kids or no kids yet: college has become a big time scam. It can't possibly deliver the the return on your money it claims it can. Make your kids stay local and take cheap community college courses until they can support themselves. You will go broke putting them through 'good' schools and get very little in return unless they are valedictorian of Yale or something.
And yes, I tried to get my kids to take technical majors but they had no interest. I caved into them and my wife (who's Dad was loaded and sent her to an elite private school). Now I see myself with very little savings when I'm in my mid 50s.
Take heed, young folks, take heed.
