After years of accepting favorable government subsidies, he has realized that his is not the flavor of the month. Now Clueless Joe wants to prop up unionized EV manufacturing. So, even though Musk's Tesla offers union scale wages and better benefits than GM or other US union shops offer, the Build Brandon Better legislation excludes Tesla from the government piggy bank because it is not a union shop. ($12,500 tax credits for U.S. made electric vehicles made in unionized factories)
Musk is lashing out about the injustice of it all. "Honestly, I would just can this whole bill. Don't pass it" "I'm literally saying get rid of all subsidies," Of course he takes this position AFTER the subsidies for building EV charging stations was passed in the anything, but infrastructure bill already passed.
Musk's whole business model for Tesla was dependent on his rent seeking .By all appearances ,his new found appreciation of letting the markets decide smells like someone who wants to stifle the competition after getting his government gravy.
So when Advocate Of Communism criticizes him for complaining after he has taken his share ,she has a point.
