The richer the rich are the more influence they have over the government and the more they are able to obtain government funds. It’s a vicious cycle. They need to be taxed or else we all suffer.
The fewer assets the government has the less it can do with the same amount of money, IE if it’s renting a building from a rich person as opposed to owning it. An example is:
Elon just said to privatize the USPS and Amtrak. If he accomplishes that then it would essentially make the government less rich in assets and the rich richer, it will increase the expenses of using those things for the government and increase the power of the wealthy. Again, means the government can accomplish less with the same amount of $$$.
I think the link above needs more learning resources like Gary’s Economics or something.
