Would Applying The Milwaukee Magnum Principle Cause Capitalism To Implode?

No. Rampant and wasteful consumerism is a recent phenomenon. Just look at the huge landfills of today compared with the small dumps of just 50 years ago. Capitalism was built on the Milwaukee Magnum Principal. It has just lost it's way today because of greed. And this is not the greed of the huge corporations. This is the greed of the small consumer who doesn't care if their precious products ruin the environment or were made by children in virtual slave labor. All that matters is getting the next new thing and throwing the last old thing out. If there were no demand, there'd be no supply.
