Over the last thirty years, the social compact that divided value produced by productivity improvements between workers and corporate/financial interests broke down. All the value from improvements (they were mighty) in productivity went to corporations/finance. Median incomes stagnated for 30 years and the illusion of growth was produced by the extension of cheap debt. It was also the driver behind the ahistorical rise in the stock market and ultimately the recent financial meltdown.
That would be bad enough, but it's getting worse. Median incomes are now on a downward track to give corporations the ability to return to profitability through increases in productivity (a massive 6.4% rise in the last quarter).
This could be an interesting trend line. Rather than keep median wages at status quo levels (as we have over the last thirty years), this is one where corporate/financial interests claw back on the gains in median wages between the end of WW2 and the mid seventies. In that direction lies complete and utter failure.
