At the recent Property and Freedom Society meeting in Bodrum, Dr Sean Gabb made some slightly controversial remarks about how large corporations, such as Tesco et al, can offload or externalize many of their costs onto the taxpayer (e.g. via local authorities building all of the road infrastructure necessary to access a large Tesco site, with its accompanying opportunity for favoured contractors to help themselves to the resultant pork).
Keith Preston, of the Libertarian Alliance (larger wing), puts forward a vision of the future in which such cosy relationships between the state, large favoured corporations, and contractors, will no longer exist.
