Sure, the problem is that the State isn't very good at delivering those services. It is the failure of the State and the State's employees to be competent that has seen the drift to extremist and populist politics in this country and others.Obviously.

Nobody can ever be trusted to regulate themselves. That's why we have laws and police and courts. That's why some sectors have specific regulatory bodies which are constituted be law. You can call them professions if you have a hankering for the Anglo-ascendency class world of yesteryear but it's just the State overseeing and regulating the actions of people who work in specific jobs.It is 'getting bigger' partly because the private sector has clearly demonstrated that it cannot be trusted to regulate itself.
If people could be trusted to regulate themselves there'd be no Medical Council or any other regulatory body.
