I believe all parents wish to see their children earn advanced degrees and are willing to pay the full cost of a long university education, even though some are financially disadvantaged.
Unfortunately, here in my country and in developing countries in general, university education has become a heavy burden on parents as well as students. Poor parents borrow money to educate their children, and poor students graduate from university only to become unemployed with a degree they can hang on the wall.
Therefore, many parents prefer for their children to learn a profession that will earn them money from an early age, rather than wasting years on a university degree they may not use in the future.
