Then why doesn't the employee do that instead of taking a job and work for someone?
And everyone has the potential for evil in them. Starting a legitimate, legal business isn't evil. You seem to think it is. If a person starts a business and only works for himself is he still evil? If he gets busy enough to need help should he turn down the extra work or should he create a job that will allow the person working for him to be able to feed himself and pay his rent? Should he only hire someone who makes as much as he does and can say how things are done?
