It got a bit more homogeneous after Walloon and dutch dialects were removed in favor of Paris french (while Flemish stayed a bit more different than Dutch but officially it’s NL Dutch).
For the sub-cultures hub in the USA yeah, there’s a lot of them, a direct result of the colonisation of the continent. But I think what most Europeans compare against is the exported American culture (from movies, music and whatever fads start there), which is pretty homogeneous (ie, mostly capitalist and individualist) but doesn’t really reflect the variety you can find “on the ground”.
Tbf, the Walloon settlement in the US (Namur, Wisconsin) is pretty small, I couldn’t find exact numbers but seems to have a population of a thousand, and the Walloon language is disappearing









Weren’t there native tribes living on the continent before the us was created?
But yeah, the land here has been inhabited for a long time. There’s a major Paleolithic site near where I live.
Seems Europe as a whole also has a distribution of small and large countries, even though the us has more of them and more land
