Salary earners end up spending their salary buying from the business owners making the business owners to get profit from the business while the salary earners end up with nothing.
No one is better. Both of them have their advantages and disadvantages. The truth is that some people can't be business owners because they don't have the capacity to own and manage the business. Especially in the beginning, it requires a lot of sacrifice and patience for a business to be successful.
They're people who earn salary and do business that is because they have the capacity to manage both. So I think it depends on individuals mindset and their goal.
