The USA was never meant to be culturally diverse. Racially (and perhaps one day even species) diverse, yes, but they're all expected to share one culture.
Oddly enough, this is baked right the fuck into Zootopia. There are NO CULTURAL DIFFERENCES between ANY of the species shown. They're all basically "American". Contrast this with Beastars, which at least touches on the fact that you're dealing with different creatures who could be expected to be coming from different cultural directions, but are being forced to figure out how to work alongside one another (and you can see how monstrous this expectation actually is.)
