Technology is the one sector of the economy where the productivity increases so rapidly that this increase outpaces the increase in the money supply. Thus, prices go down over time instead of up, while new and better products constantly bump older ones out of the market.
When it comes to technology, prices go down over time and the wealth "trickles down" to most of us. When it comes to food or virtually any other commodity, prices go up and the big financial institutions swallow up the little guys.
