So then what you're saying is if you're a millionaire then you can criticize billionaires?
I don't criticize either. I don't think a person can have too much money. I don't care. Wealth is not finite. Rich people are not hoarding all the money, keeping it away from the poor people. Wealth, for both parties, is created in the free exchange of goods and/or services.
There's no reason for anyone to tell anyone else what to do with what they have earned. If you own a house I can't tell you who should live in your house with you. If you own a car I can't tell who should be allowed to drive your car. If you're a billionaire then I cannot tell you to give it away. If you own a gun, I cannot tell you how many bullets you're allowed to load in a magazine.
This is a free country and having or not having stuff is what freedom looks like.
