No matter what a person eventually ends up doing for a living there is a certain amount of education or ability to think and reason intelligently required to get ahead in the world.
There are no guarantees in life.
Someone could get a Masters Degree and end up working in retail and another person might drop out of high school and become a world famous entertainer ( John Travolta, Beyonce, Al Pacino..etc) or college drop outs who became billionaire entrepreneurs such as Michael Dell of Dell Computers, Steven Jobs of Apple Computers, Bill Gates of Microsoft, Mark Zukerman of Facebook.
There are other instances where people have started their own local businesses,invented something, or wrote a best selling book….etc
Truth be told (most people don’t end up becoming multi-millionaires regardless of their educational level). In addition to education one needs ambition, determination, perseverance, and a little luck for things to fall into place. Almost every success story has a period where all seemed lost and the individual persisted. Most of us give up our dreams along the way.
