We have to assert that we are British, or English, or Welsh, Cornish or whatever. That's how it is done, and how it has been done down the ages, and it is how this country became the greatest in all human civilisation. It has to be asserted with confidence. Others can be let in, but only if they want to join in and conserve what we already have, and not if they want to change it. "Conserving" what we have is the main consideration, not money. When money becomes the main consideration "they" become "us".
