But the point is that the US is 100-200 years of homogenization veneer on cultures ranging from Asian to African to European to indingenous. In that sense, the US has a broader base of those enclaves within the country and less time to have built a coherent cultural identity between those populations. Europe, by contrast, hasn't forced the veneer over all of the enclaves (eg, single language), but the enclaves share a more similar historic background. It's different kinds of diversity, really. Stable multi-components versus broader partial fusion.
