What if the stuff Elon is doing to reduce gov spending actually works?

I appreciate there is a lot of (justified) hate towards Elon, but lets assume for a second he actually does just intend to get rid of lots of inefficiency and waste within government.

I know thats a bit of a leap of faith - with that said - hypothetically, what do you think it would mean for America if it actually works and by 2027 the deficit is much lower, government is much less restrictive and taxes can be lowered.

I'm not looking to discuss the likelihood of this happening - just looking to wonder what would things look like in America if it did.
