My parents paid for my college (everything the first two years, tuition only the years I lived off campus, plus a May sem class where we visited 7 countries in 30 days). The expectation and plan is that I will do the same. Luckily I work at a college, and we get 16 semesters at any of our 12 sister schools for $5K/yr (all private liberal arts schools that do well in the ratings). Unfortunately we have three kids, so one of them will not be covered (unless one of them decides to go to my institution, which would be free other than room and board, and they could live with friends in a rental we own near campus). We are saving in a 529 plan, but only because the state we live in gives us a 20% tax credit for the first $5K invested anywhere. I don't know of any other guaranteed 20% interest rates :)
