It's not about that. Would you rather live in the US or would you rather live in China (social credit) / Russia / North Korea?

But I know what you're argument is going to be: "We're going to do communism in the US, but this time we'll do it right!".

"But it's only going to be for people worth more than 100 million!": it may crash the entire stock market with the absurd amount of taxes they want to impose. If the entire stock market crashes, regular people are going to be affected (pension funds comes to mind).

Such a tax may very well have the exact opposite effect of the one hoped for.

I'm not even commenting about the next Elon Musk who might simply to launch his next Tesla / SpaceX and Starlink in another country than the US.

Is the US better with or without Tesla/SpaceX/Starlink?

Should the US even take the risk to act in a way that could prevent the next founder of such companies from creating its companies in the US?

Also to what end? Such a taxation wouldn't bring any sizeable money compared to the amount we're dealing with: $35 trillion of public debt, insane spendings, etc.

The total wealth of all the billionaires is $6 trillion. Where do you draw the line?

What about seizing all that wealth: the whole $6 trillion? (which wouldn't be worth anywhere near that amount the moment you'd seize it due to stocks and real estate crashing).

What I think: $6 trillion wouldn't even change a thing. We're adding $1 trillion of public debt every 100 days.

In the absolute best case, you "won" 600 days.

Truth is: there are people in power who hate the rich because they only one form of power, the state.

Be very careful what you long for.
