Although a university education can be an advantage, it is not always necessary for success. There are many examples of people who have been successful even though they never went to college. Also, many people who have gone to univesity are not particularly smart of successful in their later life.
In my opinion a person can succeed in life without a university education. Because education is available outside the structured university system and education is not the only yardstick to measure success. Many blue collar occupations offer opportunities for success and no degree is required. The mindset that only collage educated individuals succeed in life is a falsehood.
