I lived in Glasgow for quite a while. The most prosperous folks by quite a long way were, whisper it, NOT WHITE.
It is the same across the United Kingdom (perhaps with the exception of Northern Ireland). Most of the premium real estate is in the hands of Asians and Arabs. Most of the companies and businesses are owned by them. Take a look at London. In some of the boroughs, there are hardly any natives.
In general there felt like far less racial tension than down south. And by far the most religious tension was between those white people again. I'm getting fucking sick of them.
There are very few non-Christians in Scotland. Muslims are less than 1.5% of the population, compared to more than 5% in England.
