What you call social issues are usually just part of politics to the extent that they are important for identity. In fact, I'd say the US is one of relatively few places (in the West at least) where this is an important part of the political divide.
Immigration and law and order plays this role in most European countries with a clear divide between hardliners and softies. Preferring a tough line on those issues is certainly important for the identity of many working class males.
I don't know enough about Sweden to say if you fit this pattern, but in Denmark the divide between "social"/value based issues and socioeconomic ones is very clear. A party like Det Radikale Venstre (Social Liberals) is basically a club for those that are left wing on value based issues and right wing on economics, while the Danish Peoples Party is the exact opposite.
Is the DFP as pro-welfare as made out to be ? After all, they backed the right's economic policies pretty loyally.
