Sorry for the long delay in posting. I'm on vacation in the former Austro-Hungarian empire and I'm quite busy trying to enjoy it.
A few people, all older men, have asked me as we've talked casually about where I'm traveling if there is any resentment of Americans in the short experience I've had. The easy answer is No, nobody seems to care. To the extent that there is any resentment to be felt I think it's directed at the Germans for being obviously so much wealthier than Czechs, Croatians, etc.
The more interesting answer is, it says a ton about the generation gap that anyone from the Cold War era still thinks Europeans are envious of or aspire to be Americans. Yeah, they like our shit music and movies. The dominant sense, though, is that they just feel sorry for us at this point. Nobody's crawling under barbed wire to escape East Germany now, and certainly not to get to a country with zero paid vacation days mandated by law and in which people can work full time and have no ability to see a doctor when they're sick. I feel – and maybe I'm projecting – that people in Southeast Europe have lived through a collapsing, failed regime and they know one when they see one. And they feel sorry for Americans today the same way Americans used to feel sorry for Eastern Europeans under communism. Just replace "God, they don't even have toilet paper! They have to wait in line for bread!" with "God, they're all one paycheck from being homeless, and they can't even go to the hospital!"
America's immigration policy where white Europeans are concerned is an open door now. Nobody resents us – they see others (Japanese, German, etc) who are as wealthy as American tourists, and they see the benefits they enjoy for being EU citizens and consciously choose not to trade it for what they could get in the US, which boils down to lower taxes and not much else. They'll continue to buy our Lil' Pump tracks and our Dwayne Johnson movies, but do they want to be us? No. They think we're nuts. Right now we're the Crazy Friend who you like but want to keep at arms length. We're on our way to being the Train Wreck Friend who you actively ignore when the number comes up on the phone.
