It doesn't matter anymore.
Output is good enough - much of Google, Amazon, Microsoft, Meta, Nvidia, Broadcom, and other tech companies backbone infra or core IP is already implemented and owned by product and engineering teams in Poland and India or by foreign nationals in the US on work visas (eg. PyTorch). And if middle managers cannot manage to maintain output when faced with those with cultural differences, we'll fire them and hire people who can.
This is why you see the trope of "Indian C-Suite means layoffs and offshoring" - it's not the C-Suite that makes this decision, it's boards that decided to do so and thus hired an Indian origin C-Suite to operationalize that strategy. It's the same reason why Taiwanese Americans were over-represented in Hardware Engineering C-Suite roles 10-20 years ago when "China Shock" began in hardware industries.
It became easier to hire Jans and Jagmeets after a large number of SWEs and middle-managers in tech who were on visas were given the option to either be laid off or relocate to the old country and open a GCC during the initial COVID recession. And I may as well hire Pawel and Param as Product or Engineering Directors in MTV or SF and have them fly out to the Prague, Warsaw, Bangalore, or Hyderabad office every couple weeks.
> Americans unable to comprehend Europe has labor regulations including on overtime and on letting go of staff...
That's Western Europe (think Germany, France).
Central and Eastern Europe (think Czechia, Poland, Romania) roll out the red carpet for us, and we pay 75th-90th percentile salaries in those markets (which usually ends up being in the $80K-130K TC range) meaning we get the cream of the cream.
Heck, Czechia and Poland have dedicated bureaucrats who work with us to solve regulatory issues and give several thousand dollar per year per head subsidizes when investing in building a GCC. It's the same with India as well.
