Even when Europeans critique the United States, they're critiquing the US from the US liberal perspective.
> Why do so many sick and injured Americans end up bankrupt or die prematurely?
Because we don't have a national healthcare system. Why? Because people vote against it. The party in charge of the entire country would cut the government by half if it had the power to do so, and they keep getting elected because a large portion of the country agrees with them. Even within the Democratic party, large portions don't want a national healthcare system (though polling on this has changed in recent years). Why? Because if you have a job you probably have a healthcare plan, and a good portion of the country doesn't want their taxes raised to pay for healthcare ran by the government. Even liberals in the US have trouble understanding this.
> Why do parts of Michigan look post-apocalyptic?
Michigan is a gorgeous state (you'd know this if you were at all familiar with it) with one of the best universities in the world, and a GDP higher than most EU countries. If Michigan is post-apocalyptic, then most EU countries are favelas in Rio after a nuclear holocaust.
> Why are many of your schools still de-facto segregated? Why is there a Wikipedia article titled "List of tent cities in the United States"?
We have income inequality. We don't have a consensus on what to do about it.
> We could understand a claim like "America is really weird - we're ridiculously wealthy, but our government is profoundly dysfunctional in ways that are hard to fix, which causes a great deal of avoidable suffering". That makes sense to us. A claim like "America is the greatest country the world has ever seen" sounds obscenely callous without some very strong caveats attached.
Sure, but many Americans don't understand why you guys are so reliant and on your government and refuse to take ownership of your own lives. Many would argue that your constant need for government to provide for you is why the EU, for being almost twice the size of the US, lacks the cultural and political influence, and innovation that the US has.
The US, for better or worse, is a "get mine and don't worry about anyone else" country. Even the "left" in the US gets upset when something of "theirs" is threatened to be taken for the better good - just look at the housing situation in liberal San Francisco.
