A very nice and very relevent chart by Jake at Econompic. He always does a fantastic job of breaking down economic data into interpretable results.

The above disconnect occurred for a number of reasons (less savings, transfer payments [i.e. unemployment], return on financial assets, borrowing [credit is down due to defaults, but net borrowing is actually up], and missed mortgage payments [some evidence that people are spending what "should be" their mortgage).
None of which are sustainable.
As a result, look for consumption to slow unless wages and actual income levels begin to rise.
