After decades of consumerism, most consumers already have most of what they need/want, so in order to keep selling widgets, corporations must manufacture demand. Enough big screen TVs have already been built and sold to give every American a fully functional 60"+ screen in every room in their residence, enough lightly used ones to go around to completely negate the need to manufacture more. But profit must not go down for any reason, so they must invent gimmicks to push the latest and greatest model onto a public that can't even tell the difference without marketing propaganda.

The entire global economic system depends on the unceasing transformation of natural resources into a stream of disposable crap for the benefit of the ownership class and shareholding leeches. It's obviously unsustainable, but so are the mortal lives of those who benefit from the system. What incentive have they to save a world in which they will no longer have any stake? Better to live out their days in comfort and wealth by cutting down the saplings under whose shade they will never sit.

I say enough is enough.
