Having no freedom as a job worker does not mean being incompetent, as well as having the freedom and everything is in full control does not make an entrepreneur competent either. True competence is measured through one's application of knowledge to real-life situations and problem solving, behaviors and traits, and the internal motive or drive to perform the job, and these do not limit whether you are currently employed or you own a business that makes you the founder or CEO.
However, getting rich is another story. Anyone can get rich with lottery or from inherent properties, and they don't manifest whether you are competent or not.
Lottery is a bad example, that rarely happens, most rich people are rich because they are hard workers. There is no alternative to it, not all hard workers are rich, but all people who become rich were hard workers. You could inherit, and be lazy, but you can't be lazy and make it.
No person in the history of humanity, good person or bad person, NEVER started poor and became rich by being lazy. That part is something you have to focus on, and even lottery winners usually end up losing it all back again. So if you want to be good and rich, work hard, maybe you won't get rich, but that is the only way.
