Really? Marx & Marley said so, thus the end is nigh?!
It seems that a lot of radicals in Portland subscribe to this theory. It's kind of the left-wing equivalent of the "survivalist movement." Isn't this the same logic that left a lot of "activists" feeling rather foolish on January 1, 2000, when, like, the entire effect of the worldwide Y2K disaster was the Yahoo! website had the date wrong for a few hours?
Capitalism has gone through many collapses. Individual investments collapse. Individual investors lose lots of money. Entire industries and technologies go away. Depressions linger for years. That doesn't mean capitalism is necessarily going anywhere. It just seems like wishful thinking to me. When the oil runs out, won't the capitalists go back to exploiting human & animal muscle power, or coal, or biodiesel, or something? When the population bomb finally hits the wall, won't we be the ones to go hungry while the money guys at Intel eat all they want? I mean, isn't that really more likely?
I'm not saying that events can't come together to create a crisis for capitalism, I'm just saying I don't see it happening, and I don't think these guys on the radio really see it either. I think they're mixing up technological instability and political instability. For real, the oil age is past its halfway point, I agree, but capitalism could be here for a while, and I don't see it "collapsing by itself" anytime soon.
