The issue isn't their economic power by itself. It is their outsized political power that derives from that economic power. The more political power the oligarcs have, the less power all the other citizens have.
If anything, it’s an intransparent trade that gives Musk and the others their power. It is not a vote.
Untrue.
Everyone who bought a Tesla voted, with their dollars, to give Musk this wealth. Everyone who owns Tesla stock voted, with their dollars, to give Tesla this wealth. And everyone who voted, with their votes, for representatives that gave EV tax breaks voted to give Musk this wealth.
The man is rich because of economic and political cause and effect. Don't pretend the world that made Musk eye-bleedingly wealthy is somehow disconnected from the world of our collective actions.
