I am confused by the idea of economic progress. I check the price of underwear at WMT: http://www.walmart.com/cp/Underwear-Socks/163866 So you can get a pair of underwear for about $13.50 / 4 = $3.75 per underwear. I wish I knew what the price of underwear was say in 1930 adjusted for wage inflation, and the price of cotton (do we need to include the price of oil to transport it?). If machines make these things, and all of this stuff is outsourced to places that have very low wages, why isn't underwear close to free, or at least cheaper than it was in 1930? Finite natural resources is the biggest ally of inflation.
