I don't know in what world you are living in, but at least where I live there is nothing suggesting that public services are going away any time soon. Oh sure, there are some things that could use more private involvement, but to make some insane statement like "in 50 years there will be no public services" is just laughably ignorant.
Yes they are.
Things like transportation, road networks, mail services, phone communications, news broadcasts, gas, power, water and other utilities were once considered to be public services; now they are businesses. Public schools and hospitals have to compete with private schools and hospitals. Cops, too. Private security contractors are used more and more. Even justice is concerned, as some legal conflicts can be solved by private arbitrators instead of public courts. (Heard of the Tapie/Lagarde story?)
And on the flipside, nation states try to deal with an ever-inflating debt by cutting fundings to what remains of public services, closing down classrooms and removing beds from hospitals, forcing people to choose between shitty underfunded and overcrowded public services or expensive private offers. By and large, the heterodox financial view of public services is that they should be managed like private businesses, that is to say, they should either turn a profit or disappear entirely.
Public services are on their way out. They're the dying remnants of an extinct way of life; they have no place in the hyper-competitive world of today where the only measure of merit, virtue, truth, beauty, and everything else is how much of a profit it can turn. Public services do not matter because, fifty years from now, there will not be any of them around anymore.
And everything has to turn a profit? What about law and order then? How are you going to make money of crime? Attemtps at private prisons in countries like the UK and the US have been big failures and the center of a number of big scandals, so clearly the private sector does not do everything better then the government does.
