Civil servants or masters?

We know that in the UK the bureaucracy has much higher average pay than the rest of society, the people that create the wealth that they extort for themselves. This is not just a quirk of the UK system, it also happens in the US where the civil servants 62% more than the average worker. As too why this happens? Well because it can. Civil servants are extremely hard to get rid of, the civil service has no competition and the only constraint on the amount that it extracts from it's workforce is the level of taxation that will lead to the fall of the governments that nominally controls them. Bureaucracies, like everybody else, are out for their own self interest but unlike everybody else they have fewer constraints and can therefore indulge their self interest more.
