" Well, it's been obvious for centuries that capitalism is going to self-destruct: that's just inherent in the logic of system―because to the extent that a system is capitalist, that means maximizing short-term profit and not being concerned with long-term effects. In fact, the motto of capitalism was, "private vices, public benefits"―somehow it's gonna work out. Well, it doesn't work out, and it's never going to work out: if you're maximizing short-term profits without concern for the long-term effects, you are going to destroy the environment, for one thing. I mean, you can pretend up to a certain point that the world has infinite resources and that it's an infinite wastebasket―but at some point you're going to run into the reality, which is that that isn't true.
Well, we're running into that reality now―and it's very profound. Take something like combustion: anything you burn, no matter what it is, is increasing the greenhouse effect―and this was known to scientists decades ago, they knew exactly what was happening. But in a capitalist system, you don't care about long-term effects like that, what you have to care about is tomorrow's profits. So the greenhouse effect has been building for years, and there's no known technological fix on the horizon―there may not be any answer to this, it could be so serious that there's no remedy. That's possible, and then human beings will turn out to have been a lethal mutation, which maybe destroys a lot of life with us. Or it could be that there's some way of fixing it, or some ameliorating way―nobody knows. "
