Extreme consumerism trends downwards in a few obscure commodities and someone proclaims the end of private property. Give me break, collections of books, DVDs and CDs have always been largely worthless. Cars was never an investment tool. Real estate, stocks, bonds is property with at least some value. Put stats on that before arguing that private ownership is in decline. (I'm not saying it isn't) I'm merely saying consumerism was never about private ownership, or am I missing something?
