How hard is it to get a visa ?

1k a month isn't bad at all. I imagine if I had a million dollar saved up in 10 years, I could just move there.

And then live forever off my investments, plus as you've already mentioned, many younger people know some English.

I'm guessing for an American Eastern Europe would be less of a culture shock than say Thailand

Culture shock isn't the only thing that factors into quality of life though. There's a lot of places in the US you could go that you might dislike living in but wouldn't necessarily introduce a significant culture shock compared to a foreign country.

Just wanted to point out that out, as I've lived in Asia and Eastern Europe and despite the greater culture shock in the former, still preferred it as a long term residence. One's personal preferences and expectations for life can affect that a lot.
