You can live pretty comfortable in most of the USA too. Especially if you dont have kids.
LA is just one of the most expensive cities in America.
Where I live, a nice 2 bedroom apartment is 1200 a month.
The more “blue” a state is the more expensive it’s likely to be. Someone needs to pay for all the social services and that someone is the working people who live in the state.
The closer to socialism a state gets, the more expensive it is.
