If by visionary you mean he envisioned upping his wealth at the cost of American jobs, you’re correct. He envisioned that cutting costs at Xitter would make it more efficient than ever, yet the opposite occurred.
It’s not that he can afford to help the USA, it’s that he could afford to bankroll Trump into giving him a position in our government to further his own interests. Owner of a space company is now in charge of gutting resources to NASA and NOAA, definitely don’t see any collusion there.
He’s pushes against subsidized projects which is hilarious given how much money the government has put towards his own companies. He’s vehemently against organized labor which is hilarious given the amount of union members who support him.
