Sure. 50 years of emigration and a stagnant economy linked to a stagnant UK economy and we wouldn't have a housing crisis now. Except maybe the problem of what to do about the deserted villages, towns, countryside, etc.Though maybe we would have enough houses to go around. The population has increased from 3m to 5m during our membership of the EEC/EU, largely driven by EU immigration and reverse Irish emigration. This is squeezing our young people out of the housing market, producing sky high rents and of course a homelessness crisis.
Maybe we could do with a Brexit cold shower.
