Employment might be up, but wages (except for executives) have been stagnant for well over a decade. Retailers have been squeezing suppliers in order to maintain low prices (hello Costco, Walmart!). Discretionary spending is low due to under-employment in many sectors.
BTW: the "unemployment" figures fail to take into account people who are no longer looking for work and even worse, the masses of underemployed, people who can barely make ends meet.
