The argument is that all wealth belongs to the government and it was generous to let us "borrow" some in our lifetimes.
What a sad world.
If it was just that, it would be one thing. But the true communist approach is to use envy of wealth to foment violent revolution, and take it all into state control.
Kill off a few million middle class and above, along the way.
My hair stands on end, when a supposedly "conservative" person starts in on the misdeeds and unfairness, of those that "have."
Government makes worse decisions than private owners of wealth. Government would squander wealth on current consumption, by the permanent classes of the perpetually poor, and the perpetual government employee class. With plenty of graft and corruption along the way.
