As for my two cents:
Your exactly right. The artificially cheap inputs from subsidized
primary extractive industry send the price signal that material
throughput is cheap. The "four horsemen" of primary extractive
industry, mining, petroleum, agriculture and forest products, send
more and more material more and more quickly down the chute to
primary manufacturers. (And quickly to landfills.) This is the
imperative of GNP!
On the other side of that "bridge to the 21st century" Clinton keeps
talking about, however, lies a world in which economic health can
no longer be a function of how quickly we can consume our natural
capital. We need to focus attention on clearly attaching price
signals, and incentives, to replacing both mass and energy with
information and intelligence: thus P2!
