What Good is a Professional Civil Service?

Why arbitrary firing of civil servants is ill-advised:

I suspect many of the businessmen who think government should be run like a business lack a basic understanding of what government is; why we even have a civil service; how proud the tradition of professional civil servants is.

Professional civil servants - teachers, policemen, firemen, bureaucrats, scientists, regulators of communications, nuclear energy, air and water quality, on the job safety, roads and bridges, the environment... .

We love to disparage the lazy, obstructive government workers. But do any of us really want to see the FBI, CIA, military, our local fire departments, police departments, sanitation workers disappear? I don't think so.

I doubt anyone would like to return to the spoils system of political cronyism that existed before a professional civil service was established to PROTECT the public good against capricious dismissal of trained professionals and their replacement with political stooges.

No system designed by human beings is perfect. A system based on entrance examination scores and merit generally is much preferred to one based upon the venality of self-interested political hacks.
