Sometimes I have trouble remembering that other countries don't have the same level of background socialism as Denmark.
Coops are ubiquitous here, I rent my home from a coop (I'm a member), half the convenience stores around are part of a coop (I'm a member), the milk I drink is produced by a coop (farmer-owned, I think my uncle is a member), etc.
And all of these coops have been around for more than 50 years. Hel, even my IT-worker's union is over 50 years old.
