Baumol's cost disease famously calls attention to the fact that when there are reasons to expect steady productivity divergence between sectors, the associated product prices will diverge and this will impact consumption patterns. The fine arts sector, for example, cannot expect productivity improvements to match those in manufacturing. Fine arts prices will rise in comparison to manufactured goods as will their relative importance in people's budgets.

Look at all the garage and yard sales, the rise of the self-storage industry -- as well as the relentless accumulations of stuff in our own homes and offices.
