Detroit automakers invented
Planned Obsolesce by purposely building inferior cars that would fall apart after a few years. The plan boosted profits in the short term but the idea backfired long term as literally millions of customers swore off American cars and turned to imports. Cash for Clunkers is just another play on that old idea only now it is law at Government Motors. Funny they disguise this con game as somehow being green and good for the environment when building a new car releases 8 tons of carbon into the air.
In the larger perspective we talked about this years ago on how in the face of peak oil we would squander the last of our resources by trying to save the old way of doing business. Growth is just a euphemism for turning natural resources into garbage. Cash for Clunkers is pretty much the epitome of foolish wastefulness in our society.
