"@ JonLaw — It's worth noting that depending on your income bracket and savings going to Harvard can be cheaper than going to Berkeley after financial aid is considered"

Yes, if you never save any money, these programs work well.

I'd have to look at the calculators again, but I'm guessing that if I sent my two kids to Harvard, by the end of it I would end up having spent about 30% of all of the money that I ever earned on private universities.

I will have to go back and look at it to figure out that one.

Meaning the estimated percentage of "all the money I ever earned".
