Owing to the incapacity of the higher price-rate to appeal to the "acquisitive sense," it would appear altogether plausible to attempt to do so by utilizing the opposite strategy: by decreasing piece-rates, to force workers to produce more in order to maintain their accustomed earnings. Moreover, two simple observations seem to have held true in the past, as they do today: a lower wage and higher profit are directly related, and all that is paid out in higher wages must imply a corresponding reduction of profits.
Capitalism has been guided by this axiom repeatedly, and even from its beginning, and it has been an article of faith for centuries that lower wages are "productive."
