I moved to the US back in the 2000's and it took me years, I finally was lucky enough to find a contact at a university to sponsor a H1B. That now seems virtually impossible to get unless you work for one of those giant Indian IT companies.
Also, you might be increasingly frustrated with the state of the EU, but it ain't all roses in the US. I for one, value highly the social safety nets other countries provide. Without being incendiary, things like getting healthcare in the US isn't so straightforward.
We get that the US is still streaks ahead when it comes to innovation and capitalism. But there's so many other considerations important to gauging one's quality of life.
In the end, is living in the EU really a hot mess? What about a different part of the EU?
