The first horrifying thing is what Smilo said. The party associated with "the left" ought to also be the party of the working class (of all the working class, regardless of skin color or gender). If that isn't the case, something is deeply wrong in the universe.
That's the problem, many of the West's centre-left parties aren't really 'left' anymore, especially the Democrats. They aren't working class parties, rather they represent a set of constituencies that happen to have a working class component. The question is, is this due to the parties 'losing their way' or are we transitioning to a new paradigm with the old model left outdated?
