It sounds like you don't have first hand experience living a European life (and I don't mean just living in Europe, it's all too easy to get sucked into a bubble).

While homogenization is at work, the cultural divide is blatant to the point of being highly visible here.

Having a foot in both worlds, I don't see it. If anything national cultures are giving way to European culture (which does have some inherited traits from the US) more than anything else.
