That’s a rather broad brush.
“When I grow up I want to be a Marine.”
Who but a lib wouldn’t consider that admirable?
Secret Service, diplomatic corps (no Obama, that’s not a dead diplomat), CIA, NSA and others offer quite admirable careers that serve the needs of the people. Not every job is a useless, overpaid paper pusher in an irrelevant agency. This doesn’t even count all the lawyers who join the DoJ because they want to help, when they could be earning much more in the private sector.
The problem with the civil service isn't that its pay levels are too high (they aren't, when one adjusts for education and experience levels) -- it's that the "one size fits all" setup doesn't properly account for specific job types. Government jobs that require specialized training (law, science, engineering, etc) go begging because they pay peanuts compared to the private-sector jobs available to someone with those credentials; meanwhile, the same pay scales apply to routine paper-pushers (as a result, those jobs are overpaid).
