I confess I have no idea what you're talking about. What "addictive nature" is there in Marx's theories?

I would argue "workplaces should be democratic" (which is a very rudimentary one-sentence synopsis of Marxism) is only an addictive idea if you consider democracy to be addictive in the same manner. And maybe it is, but then you have to ask yourself -- is an idea being so good that it becomes addictive a bad thing?
