1. Elon being an annoying jackass around everyone he meets has drawn most people, Trump included, to hate having him around.
2. Several of Trump's policies that are unrelated to Elon, negatively effect him and/or Starlink and Tesla
3. Trump isn't a traditional white-power nazi. He's just a racist, old American with zero wunderlust for any Reich, and isn't going as far as Elon hoped or would himself.
4. Miscalculating this, Elon is now stuck in a horrible situation of being wrong about his orange would-be Hitler, and the moat he's dug himself between him, his companies and leftists who otherwise would consume his products.
5. Doge didn't find or accomplish anything but dismantle parts of our government that then either had to be band-aided back together by the closest Democrats or Republicans for better and worse.

Aside from "winning" the election, they've both done nothing but step on eachother's feet and disappoint one another. The levee broke.

I think Musk is stupider than people realize. He's a true believer in his grandpa's technocracy movement (plus eugenics), and so he thought "if I was in control for just a few weeks everyone would realize they should just let me run the world"

Then, he got practically unlimited power, and everyone got mad at him. He seemed genuinely surprised that people weren't praising him for his sacrifices (such as selflessly condemning hundreds of thousands of people to death)

Then he showed he was useless at buying elections, and the right dropped him

He followed Trump around for a while quietly, probably spending most of it in a k-hole. Then Trump officially broke up with him, even if he glazed Elon on the way out

Then the narcissism kicked back in. Maybe his "friends" rubbed it in, maybe his dad called him a disappointment who fumbled the chance of a lifetime, maybe the threat of legal ramifications made him bitch out - but whatever happened, Elon woke up one day and decided "it wasn't my fault, Trump and Co fucked me"

I think Elon is actually concerned about the bill to some degree, because it does stretch our debt and spending to levels that could potentially pop the global economy. I think he does feel disrespected that his work at Doge is being rolled back and everyone is distancing themselves from him. I think he is upset that he spent all this money to buy the presidency, and got a bad ROI

But ultimately, Elon is a fucking idiot with a huge ego. He didn't understand what game he was playing, and so when he lost he started blaming others

And it's beautiful. Possibly the greatest crash out in history

Publicly, Elon said Trump’s bill was full of pork and would increase spending and debt by a lot.

Voters on the right were already waking up to how shitty Trump’s bill was, and Musk just used his megaphone to let even more of Trump’s base know that it sucked.

Privately, Musk is probably pissed that Trump’s bill didn’t help his companies. These are two greedy assholes. It all comes down to money and ego at the end of the day.

Musk realized Tesla couldn't do the rebate scams if the bill passed

Trump wasn't giving him the policies/legislation he was asking for that would put his businesses at an advantage. Additionally Elon was unhappy with the tarrifs. Lastly, they both have large and delicate egos.

Fun fact: This isn't the first time they've worked together and broke up. IIRC, Trump choose Musk for some advisory role during his first term (I don't remember what, specifically). Musk resigned because Trump withdrew from the Paris Climate Accord.

40% of Tesla income comes from offsets paid by ICE companies.

Trump is killing that.

I'm putting 50/50 odds that it's an intentional, theatrical distraction from other more important things that are going on, or it's just the inevitable outcome of two malignant narcissist sociopaths being in the same room together too often. If they quickly kiss and make up I'll lean more towards the former than the latter.

There is no fall out. They both are still getting exactly what they want. It is a ploy.

This is just Trump's M.O. No reason required.

While I am sure there are real, specific reasons that can be pointed to as "the reason," the real answer is that you can't put two narcissists in a room together and tell them they're on the same team. This always was the only possible outcome.

Trump thinks Miller Light tastes great, Musk thinks it's less filling.

It's also possible that this is just political theater designed to distract people

Other than them both being dickheads

Why do you think they need more than that?

The same thing that got them together. Money.

You ever see what happens when you put two narcissists in the same room? This is what happens.

Have you heard the Tenacious D song “Two Kings”?

Musk feels like he bought a president and should own him outright, Trump feels like he's renting a timeshare on the oval office and Musk is taking up too much of his 'allotted' time.

Because autocracy cannot sustain conflict of ideas. It was just a matter of time as every political scientist said 6 months ago.
