The page linked is a short piece of left-wing discourse, also liking to a book which alleges that billionaires use their charitable funds not for charity but for money-laundering.
Unfortunately, the piece is not insightful; whether you're left-leaning or not, you see nothing new, and move on.
A transfer of wealth from billionaires to the government is a transfer of power from one overlord to another. Different overlord. Same problems.
