This argument, that Civil Servants "don't generate money"?
First, are you making out that they are uniquely privileged in having lost the job lottery and deserve to be punished, for life?
Second, it is hardly their fault that society has all manner of less-than-pleasant offshoot tasks which need constant attention. Why punish them for doing the kind of work you would, evidently, turn your nose up at?
Thirdly, why don't we let the roads crumble, so the private sector cannot get goods to consumers any more? While we're at it, why not let the schools and hospitals fall apart for want of staff or maintainance.
And try not to get into difficulties if you're messing around in boats. The lifeboats and helicopters may be private sector but the coastguards aren't.
