and this was also the case globally plus don't forget that those entrepreneurs are also Uni graduates too that choose to create a Business and be an employer of others. There's nothing to mock here, regardless of which sector you fall in, the whole idea is for you to be able to take care of yourself and yours.
The ideal solution is to have a job and then work on the side hustle and build a small business hire your staff who will take care of your business.
But leaving the job for a new business is not a good option - and you will end up in psychological and financial stress.
At times the business might boom and become successful because such businesses might requires close monitoring and attention, then how do you manage your job and your business at the same time? I had seen some people who quit their high paying daily job for Entrepreneurship and later become successful business men, I think this is just a matter of choice based on how individuals can establish a business nurture it and later grow it, while some people still prefers doing their 9-5 job, personally I prefers being an Entrepreneur where I will coordinate and organize my business to attain my desire goal in a condusive place.
