Chapter 5 examines the political economy of time that we see developing in Chapter 4. It looks at whether commensuration is reductive in ways that render temporal formulae meaningless and concludes that, because time is rich in political meaning, under the right conditions it can be a good means of conducting commensuration in politics. Much like Cass Sunstein’s Incompletely Theorized Agreements, commensuration can be performed in ways that avoid deep political conflict over essentially contested concepts. However, when similarly situated persons’ time is not valued similarly, the outcome ought to be considered a form of political exploitation that undermines liberal and democratic norms. A pattern of harsh prison sentences for African American persons or unduly long waits for citizenship among an immigrant group exemplify such forms of exploitation. In each case, no justification can be found of treating the time of one group as having less value than the time of similarly situated groups. People cannot be compensated when their time has been appropriated unjustly, however temporal formulae can be adjusted to reflect more democratic procedural justice.
