Confidence among consumers unexpectedly fell in Aug for a 2nd consecutive month as concern over jobs and wages grew.

The worst employment slump in 7 decades has caused salaries to stagnate, rocking even Americans who still have jobs. The need to rebuild savings after the record drop in wealth from the dive in stocks and home values will keep limiting spending in coming months.
