I swear I have this same conversation every month, and I think it is repeated by others like a thousand times if one searches for it, but I think it's worth it. I see your position and arguments in x.com culture a lot.
> talent concentration, excellent universities and top-tier companies
This is all just a consequence of above. And note that talent in US historically was mostly gen 1-2-3 immigrants.
> incorporate a business in less than a week
This is one is important. EU strives for it, but I think the reasons lie in the different worldview, see below.
> no unions or other such bullshit
> taxes are low
> if I hire someone who turns out to be incompetent
> best healthcare
See, you purely view this topic as someone wanting to minmax gains, profit, effort. Yes, this is easier to do in the US right now.
What kind of world do you build with all this? What does it all lead to? I envision something like futuristic Mexico where a few lucky get in the top ~30% who can afford healthcare and education, and live in gated apartment communities, businesses are owned by the top 2%. The rest of the population works in gig jobs and farms (and are a nuisance, until automation makes them unneeded).
How much of the US popultion has realistic access to that "best healthcare"? Children, elderly, disabled?
If it were up to "free markets", there would be no 5 day workweek, if you were born with one arm you'd die in a ditch, and cartelling businesses would be free to exploit the population, their privacy, time and assets at their will (just click agree on our T&C).
Do you care about these issues? You must not, you're a businessman and want to do business. But the state certainly should. And I wouldn't live in a state which doesn't. This is what everyone in the EU gets with your taxes. It's far from great, varies per member country, but this is the general idea. And this is something that US tech industry people have a hard time to get, who just look at comp levels think money and enough hustle can solve anything for anyone.
I recommend you to travel and see other types of societies. But even the US itself will undergo a massive change in the next decade with how its old powers, influx of people and world economy grasp evaporates.
