Define "easily" for us, please.

There's no such thing as "Power centers".

Money is that power.

You cannot have billionaires and them not be immensely, structurally powerful.

That's the entire point of capitalism, that resources, including labor, be directed by those with capital.

Believing you can have a single human being in control of a non-negligible percentage of all resources of a country, and they wont somehow be actually powerful or influential is moronic.

Taking the power away from billionaires literally IS taking their money.

I know, that's why I want to tax them, to remove their power.

Of course, you probably mean to remove their power centers without removing their money. But that doesn't make any sense. Money is power. You can't remove the power from a billionaire and leave them a billionaire.

"Don't want to be ruled by billionaires, peasants? Have you tried dismantling your government so they can't buy it? That will surely save you."
