Wrong approach.
Give us your version of British values, culture, social norms, world view and morals and see ow many people from other countries adhere to them. Most of the western world hs become thoroughy middle-class in almost every respect.
I am a great fan of home exchanges. I have exchanged homes with Germans, Italians, Frenchmen and Poles. In every case, my counterparts had the same basic values that I have, and this applied to every neighbourhood where I came to live temporarily as well. Very instructive.
