Government Workers Feel Less Secure?

Huh. The Pew Research Center for the People and the Press has a new study out, and among the findings is that only 46 percent of government employees of federal, state, or local governments think the financial state of their employer is excellent or good. 63 percent of private-sector employees stay the same. I'm somewhat suspicious of this number, because I think state and local governments are REALLY pinched, which is one of the reasons stimulus aid to them is such a hot topic--furloughs and layoffs are starting or already under way. But I am surprised to see government as a whole score below the private sector. Maybe private-sector workers are more optimistic? Or government workers are more likely to be conservative in their estimates of an organization's financial health?
