Elon gets to cosplay as POTUS since he can't be one. He also gets to dismantle agencies, some illegally, that give him grief (i.e., EPA, SEC, IRS, etc.). He gets to "audit" competitors within the DoD/NASA and their contracts, and more importantly, he gets to data mine American data to train the data sets on his Grok 3.0 AI. If he gets in trouble with the Feds, Trump will order the DOJ to turn the other way, like Eric Adams, or use the pocket pardon he probably promised Elon. Trump, on the other hand, gets to just go after the people who wronged him with the DOJ since the SCOTUS said he's got a "Stay out of Jail" card for official acts.
Plus he's a lame duck POTUS after this term, so he doesn't give a shit about anything else other than making him, Elon, and fellow billionaires richer. Fuck the working class with tariffs that the rich can afford day-to-day, then when the working class sells their property to survive after the economy crashes, have all the private equity billionares circle like vultures to buy it all up for pennies on the dollar. Farmer and ranchers that largely voted for Trump? Fuck them. Make it almost impossible to farm or ranch, so private equity billionaires could come in after they sell and scoop up all their property. Then they go and rehire the illegals that ran away to begin with. Capitalism baby.
Congress *could* check Trump's power with an impeachment, but the GOP isn't going to do that since Elon said he'd spend $100M to primary any GOP member of Congress that opposed Trump. They're all going to turn their heads and look the other way. McConnell voted against RFK, but I can almost promise you had he been the deciding vote, he would've voted to confirm. It's a lot easier when it's not as close as that.
Russell Vought gets to finally live his Christian Nationalist dream by deporting the browns and having the GOP and Elon push their breed kink to have a lot of kids. Gotta replace the working class/proletariats to work for the bourgeoisie billionaires that now own everything.
