"Project for Government Oversight decided to do something different than the usual method of comparing public- and private-sector salaries. Instead, the group scrutinized the actual contracts that were awarded to companies for specific tasks and compared them with what it cost the government to do the same job in-house. They looked at 550 contracts — all deemed “fair and reasonable”— for 35 different jobs across government agencies, from auditors and engineers to food inspectors and groundskeepers.
Maybe the most stunning revelation in the report is that the federal government doesn’t have a solid system for determining how much money it saves or wastes by outsourcing various functions to private firms.
And this seems like something we’d like to know: Since 1999, the number of federal workers employed by the government has stayed roughly constant at about 2 million. But the number of private contractors has ballooned, from 4.4 million to 7.6 million in 2005 (these numbers turn out to be surprisingly difficult to pin down, since records on contractors are fairly unreliable). Last year, the government spent some $320 billion on service contracts. And yet there’s no ready way to tell whether this outsourcing boom is actually saving taxpayers money."
