Without an expansionary fiscal policy, low interest rates have little effect. Companies won't borrow in order to expand and hire more workers unless they have reasonable certainty they'll have customers for what they produce. And consumers won't borrow money to spend on goods and services unless they're reasonably confident they'll have jobs.
Fiscal austerity is the wrong medicine at the wrong time.
When the spending bubble popped, it ushered in the era of the incredible shrinking consumer. Demand is weak, and companies are looking to do more with less by stretching their workforce and filling the gaps with cheap labor, even part-timers. Indeed of Brookings' 20 strongest cities have average or below average cost-of-living, and most of those cities have below average wages.
