I think this is where this idea falls apart. I just don't think there's any way in hell a company's going to start charging lower prices because their costs are less. I think retail products will still cost the same as they do now, and the companies who produce these retail products will simply pocket extra profits.
Take, for example, a compact disc. CDs cost, retail, pretty much the as they did 15 years ago, even though the cost to produce a CD has declined dramatically.
Competition will prevent this. If you don't think competition will force pricecs down and wages up in an amount corresponding to the eliminated costs, then how do you explain today's pricing and wages being competitive?
