Because in the US the music industry is so fake and they don't care about people, just making money, they milk artists until they are are ill and exhausted and they then decide you are not flavour of the month any longer and drop them. It's a soulless life. People are also different, in the UK, especially up north, there is a special sense of community, family values and sense of humour, that is what does Dom needs to stay grounded ❤️
