Earlier quoted context omitted.
Right, but should you really be blaming the people who hire the extra private policemen, or the people who decide not to hire more public ones? It seems as though it's more effective to push for more public policemen. The same applies to firemen: it's more productive to push for more public firemen than to blame the people who hire private ones due to a shortage thereof.
Both are to blame. I'm not much of a statist, but if there's something that clearly must be assured by the government by means of taxation it is the police force and the firemen. If there's not enough police or firefighters, taxes must be raised or diverted from elsewhere. Morally, I think that the people who push for private security and firefighters are doing a net damage to society.
In other words, a state-provided service is not always perfectly on-time, but if I want to hire some private service with super-fast response time for my twenty million dollar beach-front property, why not? How does me hiring a private fireman _harm_ someone else? If anything, might it not reduce the load on public infrastructure?
