That won't work with Trump. Not if you built your businesses on sectors that he is targeting, ranging from EVs to space exploration and research. Musk had to pick a side. Neutrality was never an option.
Few if any of us, regardless of wealth, have any real "agency" with Trump in office. There's nothing he can't fuck up and no one he can't fuck over. This is not an attempt at justification or absolution, just a simple statement of fact.
If you're under the impression I think any of this is a good thing, that would be grossly incorrect.
Musk's all-in fervent support wasn't necessary. He doesn't get a triple pass from having to support the fascist candidate to avoid being put up against the wall, and then again for his natural tendency to embrace things and go hardcore, and then again for working to destroy/loot our institutions because it's just lucrative business. This isn't some British comedy sketch where someone is trapped by social pressure in an increasingly escalating role - at a certain point he is just a neonazi (or "sparkling autocratic authoritarian" for the "akshually" simps).
If it turns out that Musk was showing so much support as a cover for acting behind the scenes to oust Trump, I will happily change my opinion. But given Musk's longer trend of spiraling into debilitating social media addition, I'm not holding out hope.
If your business relies on the USPS as much as Amazon's still does, you want to have a seat at the table when the administration decides how they're going to kneecap the USPS. Same with tariffs, when half of the crap they sell comes straight outta Shenzhen. See also NASA and Musk. Being locked out of the rooms where these decisions get made is potentially fatal for them.
