 On the other hand, Bentham believed that a system of laws based on the utility principle would gradually and “indirectly” evolve towards greater equality in the distribution of goods, and pointed to the historical evidence of post-feudal Europe in support of his position. In the long run the key to achieving a more equal distribution of property lay in abundance: “in a nation prosperous in its agriculture, its manufactures and its commerce, there is a continual progress towards equality” (1840 [1864], I, 123). The important caveat Bentham introduced to justify this optimism is the proviso that government must not impede this tendency by allowing monopolies, putting “shackles” on trade and industry, or placing obstacles in the path of the division of property on inheritance.
