As of today, Musk is worth $396 billion so he doesn't need any more money. Musk lost about $26 billion on his purchase of Twitter, which he did to preserve freedom of speech, not to make money. His motivations for donating the Republican PAC (not all for Trump) was not related to his personal financial gain, but to his belief about what is best for the US, similar to his strong belief about freedom of speech.
Harris received far more donations from billionaires than Trump, and she outspent Trump in the campaign. 8 of the 10 top billionaires in the US are Democrats:
Zuckerberg, Bezos. Gates. Page (Google), Brin (Google), Buffett, Balmer, Bloomberg are all Democrats. Not only did they donate more money to Democrats than Musk donated to Republicans in the last election (by a wide margin), they control media empires, search engines, etc that shape the reporting of news.
Musk has risked alienating many potential buyers of EV's who on the whole tend to vote Democratic. Further, the Trump administration is in the process of rolling back emissions restrictions for automobiles, which is not in the best interest of Tesla (to put it mildly).
Trump transition team plans sweeping rollback of Biden EV, emissions policies[
- Trump plans to cut EV support, impose tariffs on battery materials
- Proposals aim to boost U.S. production, redirect funds to national defense
- Transition team suggests rolling back emissions standards, blocking California's stricter rules
So IMO your thesis is intellectually and factually bankrupt.
Musk was born in South Africa, and became a US citizen in 2002, not by accident of birth, but because he loves this country, the principles upon which it was created under, and what is stands for (or is supposed to stand for).
