Was living there for the past few years. they have had massive property price inflation, often topping the league for the UK ( bit like Northern Ireland is now). Affordability is a major issue, and the welsh economy is massivly dependant on transfers from London and public sector jobs. If the NHS ceased to exist, there would be major trouble there. There does not seem to be a large sense of optimism, resigned to being the poorer neighbour ( albeit with a very good quality of life).
