I don't know from where in my reply did you get this notion that I was implying that we developers are/should be classified as capitalists.
Anyway, what's important is for you to distinguish between the concepts of labor as a commodity and the commoditization of labor.
These marketplaces start out as facilitators in the market to bring more efficiency and vibrancy, increase overall transaction volume and value but over time they tend to get parasitical and feed off every "host" they could infect.
So, basically my comment was a protest and critique of this specific business model of marketplaces and not to debate whether programmers have to join ranks with the bourgeoisie or not.
But if you wanna debate capitalist societies, technological unemployment and the alarmingly increasing income inequality and the overhoarding behavior of resources by and with the aid of the bankers worldwide, that's a whole new thread to engage in.
