Multiple things can be true at once, he can be wildly successful while also undermining democracy.

Think we all can agree he has had staggering successes, but they have all come from having massive capital from Paypal which wasn't anything super innovative, it just solved a convenient problem at a convenient time and was awarded handsomely. Elon has put his capital to work in various ways to become successful, not all of the ways being morally sound.

You mean because he inherited wealth? sure, that's what most losers do

All except Starlink and Tesla are burning money. I personally don't consider that "staggering success."

He has had many failures, SolarCity and xAI and X and DOGE to name a few, but he has often bailed them out with his larger ventures.

Even with his successes (Tesla, SpaceX) he has built them up in large part by bending levers of government to his advantage.
