Moral Obligation to Educate Children

Rachel Canning, 18, sued her parents for financial support to help pay her college tuition.

Her parents say Rachel moved out of the house because she did not want to follow their rules. Rachel has since moved in with a friend and wants to become a biomedical engineer.  She has a $20,000 scholarship on tap from the University of Vermont.  This will pay for one year of Rachel's college tuition.

Are the parents morally obligated to pay for the remaining years of Rachel's college tuition?  Are they legally obligated to give Rachel their tax return information for purposes of financial aid?  Is Rachel truly emancipated?  Or is she still considered a dependent of parents in the eyes of the law.
