A Parents Obligation

When does the obligation of a parent stop? I don't mean the love of a parent. I mean the responsibility a parent has to give a child-young adult-a sound foundation. We encourage them to get an education; however, we also demand they be financially responsible for themselves. Does the parents socio-economic status dictate their ideas to the child? If the parent didn't make the right decisions throughout his/her life does the child suffer; or, the childs education? We want to teach them responsibility by making them pay their own way; however, learning is a responsibility as well. I think we should teach the child to delay gratification and find redemption as a doctor, lawyer, or, even greater, in the academics....
