This is in a big city. Go to immoscout and you can find 2 bedroom apartments in Hamburg for 900€/month. If you think the average person in Munich makes 3300€ net you are delusional. Not everyone there is an automotive engineer. Plenty of people just push paper in an office or stock shelves in a grocery store.

Germans are poor as fuck. Most don’t even make the $3300 you listed here, so you can live with way less than that. A realistic guess would be around $1300 plus health insurance if you don’t have a car.
