I'd love to go back to Europe...for a while. I'd love to see my aunt before she dies...I already missed my uncle. I'd love to see the adults that were 3 and 4 and 5 when I was there 30+ years ago...and meet their kids.
I'd never manage to live there. If I'd stayed as a teen, I'm sure I'd have loved it. As an independent American, I can't imagine living in a country that would force me to get training and a license to buy hand tools, to clean my own chimney, to work on my car or house, or any other "Do-It-Yourself" thing. I can't imagine living somewhere that makes overtime literally illegal to free up jobs for everyone who wants to work. I can't imagine paying 50% more in taxes than I already pay.
Europe was beautiful, but the US beats it hands-down, every time.
