Many working-class Americans, though, were not as enthusiastic about the rise of economic indicators. This was largely because they believed the human experience to be “priceless” (a word that took off just as progress became conceptualized in terms of money) and because they (astutely) viewed such figures as tools that could be used to justify increased production quotas, more control over workers, or reduced wages. Massachusetts labor activists fighting for the eight-hour workday spoke for many American workers when they said, in 1870, that “the true prosperity and abiding good of the commonwealth can only be learned, by placing money [on] one scale, and man [on another].”
