Actually a much higher number. 30%. Having said that, I want both my kids going to college. I liked your take on the cost of living and jobs paying more in California, which would apply across the board to University's and Private Schools as well in California.
My main purpose was for people to consider all options when looking at getting financial help through a college scholarship, just as many have mentioned getting both athletic and scholastic financial aid. Saw an interesting article on Brown where they were having trouble competing vs the other Ivy League Schools for people making 60K - 200,000K, which is a bit of a dead zone when it comes to paying for your kids college. Too much money to get aid, not enough to easily afford college.
