As for domain specificity:
I don't know any Europeans who'd prefer to have American healthcare.
I don't know any European technology companies that hold a candle to the sheer breadth and depth of capabilities brought into the world by Google, Apple, Microsoft, Amazon, Nvidia, AMD, Intel, OpenAI, or Anthropic.
Yes, Mistral, Nokia, OVH, and SAP exist, but compared to the alternarives, they exist in the way the American healthcare system exists compared to its alternatives.
As for granularity:
Perhaps we want American style governance for building the tech, but then European style governance for running it?
Selfishly I think my American healthcare is better than anything I ever had in the UK. I can see a doctor within 2 weeks even a specialist, I can actually get a sleep study, my doctor will actually listen to me rather than tell me I'm just getting old, go home and take an ibuprofen.
There has to be an interesting commentary here regarding the necessity of productive endeavours that pay taxes and fund local governments and drive investors portfolios into the black, all funded by useless largesse.
