This is only one of Steyer's philanthropic ventures and he is one of 40 billionaires, including Warren Buffet and Bill Gates, who in 2010 pledged to give away at least half their fortunes to worthwhile causes.
When it comes to the environment, to say nothing of most of our other prolems, I am inclined to accept Pogo's famous dictum, "We have met the enemy and he is us." Pogo was not, I think, referring to possums—the anthropomorphized little cartoon character was referring to we human beings. We are all, or at least the great majority of us, responsible for the despoiling of our planet. Not only capitalists drive their cars too much, buy homes bigger than they need or buy too much stuff—most of us do, capitalists, communists, conservatives, liberals and socialists alike. Capitalists have far too much power, but that's largely the fault of our democratic laziness, not their fault for taking what we allow them to have. We may not have voted for the corporate-friendly Harper government, but we supinely accept the corrupt electoral system that put it in power.
Scapegoating the capitalist class may allow us to absolve our favourite classes, the middle and the poor, of responsibility and help us evade our own guilt, but it won't help us deal with the environmental challenge because it doesn't face the truth. Pogo did, and ultimately so must all of us.
