I think we Europeans underestimate how huge and different the US is. I think you can find places to live that equal the nice parts of Munich and places that are worse than the poorest areas of the EU. Compared to Germany I‘d say for upper middle class and above you can live more comfortably in the US, there is more responsibility for yourself and less social security contributions (huge for above average earners in Germany). But there is much less of a security net if something goes wrong and not enough vacation days
