Boo hoo, who cares? Their inheritance and wealth should have been taxed at a rate that forced them to work. The fact that the system allows people to live off old money and never contribute anything proves that there’s a problem. Let them work at a fast food chain if they have to. Force them to see how real humans live.
So basically you’re a communist. What right do you have to take their money. As mentioned by other posters, someone in the family worked hard, took risk, probably struggled to amass their fortune. Now you want to steal it from them basically because of jealously. The money is still involved in the economy via investments and the stock market. No one is living off a vault filled cash.
You can make the same statement that you made about people who live of government benefits and various charities. You can argue that they contribute even less to the economy that these “old money” billionaires do.
