Can you define profit? Would a doctor be allowed to earn more than $200 per hour? $300 per hour? $400 per hour? Is a doctor allowed to be paid per procedure or time?
How much would you want to sacrifice your 20s and early 30s? How much would you need to work in the middle of nowhere where your kids won’t have the best opportunities?
I updated my comment, I mean a for-profit entity versus non-profit, which the IRS already defines.
Not-for-profit entities can still pay market rate wages to employees and owners.
