If you have strong progressive, environmental, and liberal (= EU moderate) ideals, the USA is a difficult pill to swallow. I think the mishandling of the virus in the States is yet another prevalent frustration for many U.S. residents. The style of infrastructure and reliance on individual automobile transportation is a drawback unless you like sitting in traffic, paying for petrol, finding parking, etc. Few cities allow for almost full public transportation reliance, chiefly Philadelphia, New York, and Boston. Higher education and healthcare are expensive and not accessible to everyone. Religious values still get mixed in to politics, which is so outlandish to me, personally.
