Not all government employees get benefits like the post office. A great many, if not most, pay for their insurance like the employees of any large corporation. They pay into the govt. version of a 401k, get a normal size matching contribution, and so on. That's federal employees, in the working ("blue collar") grades.
Yes, I know. I worked for the NPS years ago. Of course when I say the entitlements have to stop I am not referring to people who don't get massive entitlements.
