Yeah, I read in some car magazine somewhere recently while waiting, that Tesla didn't need the tax credits anymore, but the other big automakers did because their assembly lines weren't built to handle mass production of electric vehicles. Tesla has the largest stamping machines for sheet metal in the world, from what I read and their cars were designed from the ground up to be electric. The other car makers are just converting their gas cars and having problems getting places to put the batteries. Motors also are different. So yeah, they need the tax credits. The article said without the tax credits, the other automakers couldn't make money, and sometimes even with the tax breaks.
I think Musk was more ticked that the DOGE cuts were not in the bill. Also, DOGE is still at work without Musk. From what I understand they are trying to audit the Defense department. They did find illegals getting food stamps and welfare, dead people getting social security, and checks being written not knowing what they were for. DOGE has a long way to go. Without Musk there, it is harder for the left to find a scapegoat to blame things on.
However, both should have kept their mouths shut in public. Musk is right, more cuts are needed. Trump is right, we need the tax cuts. 45% of Americans don't pay income tax anyway, so those that work or have retirement income have to pay the taxes. So the tax cuts are mostly for the middle class and rich anyway. Mostly middle class as rich get tax write offs for reinvestment in their business or such.
