Of copurse you could pretend that there are really a lot of Americans frustrated by their inability to become French , but I seldom hear of them.
I consider it well established that the USA offers a better deal to thy common man than any European country .My personal experience haveing been there lead me to settle here , your personal experence haveing been both places is apparently not so diffrent .

The French do not require anyone to 'become French'. They merely prefer that immigrants learn the language and accept the usual French ways of behaving in public. Other than not walking about in cowboy clothes, American Indian costumes, or packing sidearms, I can't think of any ways that a normal American would offend the French in any way.
Most Americans have no real problems with burkhas, headscarves, and religious ornamentation, after all, and that is what ticks the French off the most these days. I spent 16 days all around France and had a great time, and did not note any hostility to me at all, and my French is not that great.
Most Western Europeans do not even consider coming to the US seriously. Young university graduates frequently find the lack of well-paying jobs and a sense of adventure the main reason for wanting to work in the US. Those that get married to US citizens tend to stay, others just go home.
Mostly it is not the 'common man' that comes to the US: it is far more often university graduates, especially those with good skills in English that come here.
