Why would people need to bend over backwards to build good things?
Nobody gives their all for 5k/mo.
Not sure of the relative costs of housing in San Francisco vs Berlin, but it doesn't feel like a massive difference. Personally I'd rather live in Berlin on €112k net than San Francisco on $134k net
I work in the EU for an American company. The consensus here is Americans work more, but not harder. We deliver better work in less time.
The edge Americans have is a can do attitude and not being afraid of failure.
Your perspective of "delivering more work in less time" is cute. Put yourself in a pool of 95th percentile of engineers on the market and you will soon find that your experience is not representative.
