Cool little article, actually. I was very amused that they adopted the Economist's "Big Mac Index," but expanded it to hours worked, rather than just price vs. exchange rate.
I also want to note for everyone's reference that NYC kicked the SHIT out of all comers on the expense of clothing, both men's and womens. (Also kicked everyone's ass, including usual claimants Tokyo, London and Hong Kong, on apartment rents, but that's to be expected - though London about as outrageous as NYC when comparing the cost of rent vs. the cost of everything else.)
