Of course there's a point. Workers en masse will only increase their class consciousness by acting in their class interests. It's dialectical. When people fight for their class interests in a union, they realize they're the working class. With the right political influences (this is where orgs like communist parties and the IWW come in) they will hopefully realize "oh shit those guys over there are also the working class". With no class consciousness, what you call the labor aristocracy can't do anything at all, domestic or international.
