I've often wondered why American Unions are unique in the world that as a parasite they will destroy the host corporation. The rest of the world's unions won't do that.
A)The role of unions in the decline of American industry is greatly exaggerated here.
B) Where unions are strongest, they are in very homogenous countries (Japan, Germany, Scandanavia) that have a more natural inclination towards collective cooperation,less low IQ populaces and more nationalistic trade policies.
