A good friend of mine came from a mining family in South Wales, is he working class

He now employs 100's of people and just picked up his new Rolls Royce Ghost yesterday, is he upper class now

No, he's my mate who I have a drink with down the local pub, he's treated the same as anyone else down the pub. Class is how other people see you, I treat everyone equally irrelevant of what car you have or the size of your bank balance
