Rich doctors is what makes them great.
Personal wealth is what drives people to be the best at what they do. If you take that away, then theres no incentive to achieve.
If I told you tomorrow that your job is now getting a 20% paycut, and everyone, from the CEO to the high school intern is going to be paid the same amount of money, minimum wage, then you would be furious. You worked hard to get where you are , achieve your position. Why should you take a paycut?
What makes you think thats any different when its gets to someone making millions of dollars a year.
Its easy to say "they have too much" because you make 1/1000th their income. Im not in favor of rich people telling poor people how to live, or vice versa
