From my experience working culture is just strongly aligned with incentives. Put a Norwegian in Silicon Valley and suddenly he gets equity, his manager is a former developer (not an finance/hr person), his visa is dependent on work, his salary is top 5% and he is well respected.

Seen plenty of Americans that got comfy in the nordics (also efficient but 40 hours max).

Also seen other countries politicians change rules that directly affected how hard people work. It’s not rocket science and programming is one of the most fun jobs to be doing so plenty would jump at the opportunity.

Instead I see people go home and try to code something at home to increase their salaries.
