Absurd late-Soviet Chernenko feel. Both Europe and USA are in deep trouble so it shouldn't be pissing match. But I have many American friends who once making their millions left to live in Europe, you might ask why. It's because their signature experience of USA is stuck in traffic looking at an obese single mom in capri pants by the side of the highway with a mulatto kid in front of strip malls at best; or having your week or year ruined by a false harassment accusation or some absurd lawsuit (often redistribution/lottery by other means). We can quibble on house size, food quality, life expectancy (prior to Trump USA had a falling life expectancy caused by overdoses, suicides, diabetes...about 6-10 yrs after your post-2007 "boom"), etc., but the stress, overwork and wretchedness of life in America especially for younger people, who now have no path to building wealth, is unequaled in the developed world--they have no pleasure or freedom to make up for it either.
In 2007, the standards of living in the United States and Western Europe were similar, and most people don’t realize how much things have diverged since the US boomed after the global financial crisis and Europe didn’t.
They don’t fully understand how we’re living and we don’t fully understand how they’re living; even when we visit Europe as tourists, we don’t see their tiny, sad flats and their depressing grocery stores.
That is why Europeans visiting for the World Cup are going to, like, a Waffle House or a Taco Bell and losing their minds. Stuff we don’t even like or care about is wildly superior to everything everywhere else. We have no idea how rich we are.
