Some security clearances can take more than a year to obtain, and the top levels need to be re-investigated on a regular basis.
I don’t think you understand the enormity of handling all of the administrative duties and security clearances for all of those people. It’s much easier for them to go through a company.
This is one of the things that far too many people do not understand about govt work. It takes a tremendous amount of resources to recruit and train people, and the sheer number of employees working for the government is unfathomable for most people who work in the private sector, even to those who work for very large corporations.
By using companies, it’s easier to keep these individuals in the “govt fold,” where they might work for one public agency, and then another, then another, and then back to the original agency…but all under the control of one company. By using the company, all of the administrative work is streamlined and, once the relationship between company and the various govt agencies has been established, it’s easy to just tell them that you need a person with x qualifications for x amount of money, and then that person arrives as soon as they are needed.
And yes, it does prove my point about privatization being more expensive than the govt having its own employees. The privatization movement wants to **expand** government (especially as it relates to expanding government spending for private contractors), and they spend a tremendous amount of money lobbying to get this done. With govt employees, while they might lobby for better pay and/or working conditions, they do not usually lobby for expansion in the way that private contractors do, and they cost less per employee.
