Unions are leftist trash that often lobby for things like bailouts that enable corporations to even exist in the first place. The only purpose for a union is to legally protect the business through government regulations while trying to bleed the workers as much as possible through union fees, which is the only reason any union even fights for wage increases.

Unions are in part responsible for the corporatist state that (mostly western) society has gotten to. Because collectivism is a cancer.
