I think that Americans repel Europeans' lifestyle. Americans are terrified of becoming like Europe.
Or of embracing European values system.
Which is based upon social equality, and that is guaranteed through the over-centralization of the State.
Americans have been afraid of a lot of different things, although America's values and perceptions of Europe were formed at a time when Europe itself was quite different from what it is now. On a practical level, when America had become newly independent, we were still relatively small and weak, so our main fear was the threat of falling under the thumb of a more powerful European power. That fear subsided as we became stronger, but it never really went away entirely.
Overall, Americans' attitudes towards Europe have been somewhat odd and inconsistent - and very often rooted in stereotypes.
For example, I've heard many Americans extol the greatness of French wine, French cuisine, French fashion - as being the pinnacle of sophistication and refinement. High-class luxury and elegance. On the other hand, Americans wantonly reject a French system of measurement which has become the standard the world over, just because we don't like the metric system.
So, when it comes to becoming like Europe, we like the things about Europe we like - and discard the things we don't like. Of course, don't all have the same tastes or agree on everything, so it's not all that cut-and-dried. The general fear of socialism and communism in America is not because those ideas originated in Europe, but because generations were raised to believe them to be grave ideological threats to the American way of life, both in terms of a threat to religion ("godless communists") and a viable foreign threat as the USSR became more powerful.
Within that geopolitical framework, America's perceptions of Europe was that they were weaker than the USSR and potentially threatened with being overrun. Essentially, they were viewed as a kind of "damsel in distress" being threatened by a terrible dragon. This was also the idea forged in Americans' minds regarding our involvement in the World Wars. Most of the countries of Europe were seen as too weak to be able to withstand or defend against German aggression, so they needed the manly power of the U.S. to come and rescue them.
Americans tend to fear anything that might be perceived as weakness. A lot of Americans might see Europe as weak, and we don't want to be weak like they are. That's why Americans support a Second Amendment over gun control. I think it also relates to Americans' resistance to socialized medicine, since it seems to go against the idea that "only the strong shall survive." They see government intervention and helping people with social programs somehow violates some laws of nature they adhere to.
As long as the US population was small...the unbridled laissez-faire didn't produce so many damages.
Now the social inequalities are really horrific...and shock us Europeans.
Billionaires living in luxurious mansions and homeless people in most big cities.
And Americans are okay with that.
Yes, although not all Americans have been okay with it. I've heard some Americans warning against the fiscal irresponsibility and geopolitical recklessness for as long as I've been alive. But many more Americans just didn't seem to care, or they thought it was all too negative or gloom-and-doom, so they didn't listen.
