Money isn't everything. If you're making enough to be comfortable and don't totally hate your job, your co-workers, and/or your supervisor, you should count your blessings.
Patman, the government is wonderful at providing stable / secure employment. If you do just enough to get by, it's the perfect place to stake out a career. However, if you have any inkling of going above and beyond your job duties and want to move up the ladder, you will be sorely disappointed and frustrated. Promotions and advancement simply aren't correlated to how well you are doing your job. I've seen far too many examples over the years of people sliding into positions of authority simply due to what appears on the surface as an all too cozy relationship with management. If you dare speak your mind or challenge the people in power, you're going to remain stuck exactly where you are until someone else takes charge. Such is life.
