Solidarity with what?whom?
-The EU and its undemocratic processes ("You voted against?- Vote again and get it right this time Ireland"), unsigned- off annual expenditure , huge waste, massively expensive protectionism for inefficient farmers, beaurocratic arrogance and inefficiency?
-People who don't see the opportunities around the world and go for them?
-Those who enjoy high taxation, massive surveillance, gloomy climates?
It doesn't sound a very attractive proposition.
