The increase in productivity IMO results mainly from technological changes that reduce the capital outlays required for highly efficient production, and thereby reduce dependence for employment on giant, capital-intensive organizations that can afford the capital outlays. In that case, it would make it harder for capital to collect the gains from productivity. Generally the rents that can be extracted from providing anything depend on the amount of competition with available alternatives. 250 years ago, the propertied classes enclosed the Commons because they couldn’t tolerate the existing level of competition from alternatives and wanted to suppress them. Now the alternatives are springing up faster than the pigs can enclose them.
