Yes and no. American salaries are great but our cost of living is insane. The amount of time wasted in the US doing basic stuff also can't be discounted. Our cost of healthcare adds up, as does the cost of everything here.
I think this data shows that a lot of Americans are waking up to our brand of "freedom" being bullshit. The American dream is a bit of a myth nowadays.
Americans lie to ourselves. If one isn't wealthy in the US, think top 15%, you're better off living outside the US. But Americans are "not yet billionaires" so most of us don't realize this. Our media pumps our hubris and egos using "freedom" and nationalism. Most Americans never travel outside of the US and believe our lives here are infinitely better than anything else in the world. It's something I see constantly when I talk international stuff with rural Americans(and the suburban cosplayer), an absolute fantasy version of the world.
