I would like to think you are right but there are too many bubbles. When I lived in London there was so many different bubbles, mainly different cultures but they all thought differently. They seem to all live in a certain part of town in their own tight knit communities.
What stops bubbles being closer and working as one will be the three main stumbling blocks culture ,religion and race. Where I live there is still so much hatred. When the whites were in power here the blacks and Indians were disadvantaged and 24 years later it is worse. The whites and Indians are disadvantaged in business and is racism in reverse. There is so much resentment between everyone when you dig deeper. The perfect bubbles are a long way off.
Yeah, those three things, arbitrary lines in the sand that a breeze could blow away yet, we keep marking it again and again.
