Friedman's theory of income redistribution up after being down for the count

Many years ago McKenzie set out to expose the hidden assumptions underlying the orthodox case for the collectivization of charity as put forward by Friedman. In doing so he argued that collectivization may reduce the degree of transfers and this will necessarily make the poor worse off. I demonstrate that McKenzie's analysis contains hidden assumptions of its own and that even if there is a reduction in the level of transfers it does not necessarily follow that this will result in a Pareto inferior redistribution.
