Can anyone with more knowledge than I throw some information to be rationally optimistic that Musk won’t totally overthrow our government/collapse our economy

Basically the title. Before anyone asks, I’m calling my senators and representatives offices daily demanding they take action against Musk’s hostile takeover of our government. But what i’m wondering is that if anyone has some useful information that could help assuage fears that the US will fall to ashes. I’m currently abroad for another year and a half until I graduate where I will most likely have to return to the US (stricter immigration laws here). Maybe I’ve been scrolling “prepper” subreddits for too long but they’re all convinced that it will come crumbling down soon. Could anyone throw some rationality onto this? Will checks and balances kick in?
