Unfortunately, there's a lot of gov't jobs that you can't cut. For example, I'm a federal correctional officer in a prison at the moment. You really can't lay me off, b/c you'd be endangering the safety of the other officers by not having enough supporting staff to supervise. Many other federal LEO's are teh same way.
I have a lot of respect for what you do. I did social work with juvenile offenders. That said the Prison and your position could be contracted off to a private firm, like Texas did, and pay less. I am not advocating that but if the government can sell roads to raise revenue they can other things as well.
Privatising prisons only leads to higher incarceration rates which is probably why the US today has a higher incarceration rate than the rest of the world combined!
But the government could examine why there are prisoners locked up for relatively minor offenses (ie: narcotics, etc.), and downsize the prison system that way. Make no mistake about it, no federal job is totally safe and immune to downsizing.
Some of you don't seem to understand. Prisons is one of the biggest industries in America. Think about it. Tied in with construction, food service, medical community, the "criminal justice system" (what a joke); there are megabucks involved.
Ahnold S. just proposed sending a lot of Calif prisoners to Mexico to save money. So correctional officers can and will be cut in the future.
