And yet GP did, and others more like him. FWIW I had two German bosses who emigrated to the US(one to California, one to Atlanta), so the US is clearly an attractive place for them and they say they loved it there just like GP.
The majority of Germans talking about how much they hate the US, have never lived there but they hate it nevertheless because it's a populat thing to hate in Germany, and also they don't work in tech, or need to rely on the welfare state, or are already from well off families where the lower local salaries make no difference. The ones working in tech who don't rely on the welfare state, are quite open to the idea of moving there for the right money.
Sure, if GP was one of those Germans from a mid-upper class background with a nice inherited Bavarian house (unaffordable at any German working wage) then immigrating to the US makes no sense as he already would have enough prosperity at home, but if you have no wealth and want to build it, then working in the US tech sector is much better than working in Germany.
So no, a blanket generalization cannot be made of "Germans wanting to move to the US", as that highly depends on their social/wealth class and career.
Edit: seems I upset the apple cart with my comment. Sorry, next time I'm gonna parrot the HN accepted "Germany-Good, US-Bad" party line if that pleases the crowd.
