You obviously don’t know very many government workers or the nature of their jobs.
I know enough,and I also know that as a group, they are no more altruistic than anyone else, like the author would have us believe. In fact, as a group, IMO government workers are less so than private sector employees, because it is a heck of a lot harder to get fired from a government job, at every level, than a private sector one. Job security is a lot better for government workers over the last 50-60 years than out in the real world.
