Hugh Stretton has been a persuasive advocate for the competition-enhancing role of government agencies in the private sector. His example was the South Australian Housing Trust which apparently operated on a commercial basis to provide alternative accommodation in the marketplace. Keeping the private sector honest, so to speak. Can people provide other examples of this kind of government function? General insurance in NSW?
This is not a rheteorical question, I am open-minded about the role of government agencies (and for that reason I think privatisation and regulation/deregulation need to be treated on a case by case basis).
