The choice is theirs: they can give up their ill-gotten wealth directly (philanthropically),

This is wishful thinking, if you wish in one hand and shit in the other which fill faster.

or they can be taxed out of existence (peacefully), or they can be fined out of existence (criminally),

These two options are at the barrel of a gun, so violently. I don't know why you don't seem to get that. Whose guns you may ask. Theirs. So more wishful thinking.

or they can be guillotined out of existence (violently)

We're here. Please catch up. However pointless violence will get us nowhere. A proper revolution must have goals to upend the current system and replace it with a better one. Much ink has been used to model this more can be read about it at marxists.org

This is how the means of production is owned in modern society. Shares. The problem isn't the idea that corporations look after shareholders. The problem is that the workers aren't shareholders. Workers are compensated primarily with dollars; executive-level management is compensated primarily with shares. When the worker starts receiving shares of future profits along with their hourly pay, the major problems are solved.

This is a continuation of the capitalist system and would be a tragedy if we revolted and got this.

Edit: rewrote some stuff, I should be less glib you seem to be earnest.
