I just have a thought, and I have twin daughters, one of whom wants to attend a $60K a year college.... I will happily help the best I can as long as she is a good person who works hard. But once a child turns 18, I think all requirements to support said child, should be over. Age 18 makes her an adult... so why would parents HAVE to support her?
Again, I will be supporting my own kids with college the best I can.
