Our educational system doesn’t teach enough about self-employment. It’s focused on theory that doesn’t necessarily apply to the real world. I concede there are some exceptions to this rule.
I can say for myself that my business degree was somewhat useful, but still has a lot of theory in it that hasn’t been so useful. I don’t think it would prepare me to be a full time entrepreneur.
Having said that, the education system has to evolve to meet 21st century standards, expectations, and challenges.
