There are different reasons why people attend college, just like there are lots of course options to choose from. Parents always encourage their wards to get a college degree since it ensures some kind of social integration, creates some kind of exposure which is necessarily for mental maturity.
Pathetically, people go through college learning every other sphere of life (from laboratory works to arts and science and management) without learning what is most vital as far as our society is concerned – which is the process of making money. That is why many people graduate from college and find it difficult funding for themselves.
