 Second, in his main discussion of it, Nozick maintains that this proviso is readily satisfied in free market  economies.[27]  This is in part due to the strong tendency of the rising tide of such economies to raise up all those who are willing to swim with it (177). It is also in part due to the low baseline set by the proviso. Nozick never carefully spells out that baseline. But it must be something like how well off the individual under consideration would have been had all natural stuff remained in the common or, perhaps, how well off that individual would be (over his lifetime) were all natural stuff (or even all owned stuff) now returned to the common.
