Because you suffered, sacrificed, so should others.
I'm sure your kids have tons of empathy.
Have you taken a moment to consider those who can't afford to pay for their kids' college even though they work hard, sacrifice, and deeply want to help?

You're right - there are a lot of other parents out there like you: wealthy, priviliged, and narrow-minded.
Giving up a trip to Barbados or a BMW doesn't win you father of the year.
(Oh...and I paid $75k toward each of my three kids' educations, so don't make a fast assumption.)
