Love Europe, it's beauty, history, etc.
Don't know about living there full time
We have everything we possibly need in the USA
It's the greatest country on earth
I loved my RU experience. But college is getting insanely expensive here and nothing is being done about it.
Europe has better food, more attractive women (and I'm sure women feel the same about European men), the cost of education (and healthcare) is free or close to it, and the sights are mostly more beautiful.
Literally any American who has gone there, spent time there, would tell you that.
More and more people are taking American salaries and living abroad, and not just in Europe. A ton of younger people are living in Mexico and other parts of Latin America and loving it, and retirees moving there.
I didn't study abroad, but I did go to Europe after graduation, and now as an EU citizen try to go back at least once a year. The world is way too big to just stay here, as much as NJ is one of the places where you get more of a global taste.
