The income tax started as a "tax the rich" tax. It only affected people making over $25,000 a year back a little over 100 years ago. They adjusted it down during WWII and it never went back up.
The libs want a net worth wealth tax. Rich people own factories, or stocks in their companies. If all rich had to pay a "wealth tax" they would have to sell off what they own to pay the tax. Eventually only foreigners would own all our factories, warehouses, retail shops, etc. Why, it wouldn't stop there. My home is worth about $450,000, why should I pay tax on my home that I bought years ago for $225,000. If they lowered the wealth tax, I would have to sell my house to pay the tax if it became lower because they took all the money from the really rich and worked their way down.
Liberals think wealth is a finite pie, but wealth can grow. You get a piece of land and build something on it, it goes up in value. The value of something is paper, not real worth.
For instance Elon Musk had to sell some stock in his company Tesla to pay capital gains tax. He didn't have cash. His worth is tied up in Tesla factories, battery factories, solar panel factories, and in SpaceX rocket manufacturing. Not cash. Sure he is worth $180 billion, but that is not cash, it is factories. Same with Bezos and Amazon. Most of his wealth is tied up in Amazon factories and shipping terminals, not cash. My wealth is tied up in my home, not cash.
Taxing income is at least is taxing the cash you make, not on the value of your store, factory etc. This wealth tax they are telling lies about is a back door way for the government to take your property and stuff if you don't pay the taxes. This is pure communism. How about the government stop spending money on things that don't produce any results. $4 trillion on welfare and food stamps since 1965 and we still have 13% poverty like we did in 1965. No results, just waste.
