Often times an experienced employee who is an industry veteran knows more about how to run the business than the business owner does but sometimes he did not want his own business for various reasons (doesn't want the risk, wants to spend time with his young children, has a big mortgage, etc). For example you can have a first time business owner with minimal industry who opened his first restaurant two years ago and he hires a chef who has 25 years experience and worked at 15 different venues. That chef has seen the successes and failure and what worked and didn't work under 15 venues with all different managers etc and has a good reference bank of experience.You being an employee at multiple places does not mean you know how to run a business any more than owning stocks does.
Just because someone owns a business does not make them more knowledgeable, qualified or superior to their employees.
