In a 2 parent household, they shouldn't be forced.
Now, in the case of a divorce if before the divorce there was a plan for the kids to go to college, then maybe a parent should be required to pay.
I have a requirement in my divorce decree to pay 2/3 of my kids' college expenses. I freely agreed to that at the time because I did not foresee that one kid would look on this as an entitlement and decide she could demand money on the one hand and be horribly disrespectful and cruel on the other.
If I had to do it all over again, or would be advising anyone else, I would not agree to an entitlement for an adult in a divorce. College costs are not a right for a kid. A decent level of respect for a parent should be an absolute minimum. Live and learn.

Except the "kid" is an adult. This is beyond patently unfair. It is immoral to require a parent to pay for something of this sort. Parents are people too.
Could you share the logic in your position?
