Often those who applaud the culling of civil servants fail to think through the implications. The work of government still has to be carried out. If/when that work is privatised, or more likely, quangos are created to do it instead, costs rise.
Capita, Serco and G4S spring to mind, as do the unlamented Regional Development Agencies of the noughties. Certainly the RDAs employed former civil servants at inflated salaries - who paid? Correct, the jolly old tax payer.
Culling civil servants is a wheeze, a sound bite. Nothing substantial comes of it.
