Personally, I think it is not illegal for parents of poor families to give up going to college if they really have no money and can't afford their children's tuition, and the children have reached the age of 18, because it is not the legal obligation of parents to let their children go to college. Strictly speaking, it is not illegal for parents not to let them go to high school. It is illegal only if the nine-year compulsory education stipulated by the state is deprived by parents. However, if parents really have no money and prevent their children from going to college, they may be really desperate. There is no way out. There is usually a way. Who doesn't think about the children's future? Sometimes a penny beats a hero. No money is really the helplessness of this world. Parents who want to be children should also cool down their parents' hard work. When parents are unable to raise tuition fees, they can also find their own ways, such as asking classmates or relatives for help, or raising money from the society, or applying for subsidies or tuition fee reductions from the government or schools, or applying for student loans from banks. Anyway, don't give up easily!
