I'm not particularly fond of the "candy" example either. Here are some others: Two artists expend equal amounts of labor making paintings, sculptures, whatever. The one whose art is popular for some subjective reason will get far higher prices for his work. Even releative values change with technology: I'm sure all of us have spent a month's labor or more on a computer that is now a doorstop. The computer didn't change--it's just now worthless because we can get a more powerful one for a day's labor now. --LDC |
