Another metric for aggregating utility is provided by political systems.

In democratic systems we can use voting patterns as a binary indicator of the relative utility that voters have for various political candidates or ballot measures.
Of course because all human societies feature inequalities of wealth and power, both markets and politics are flawed instruments for measuring social utility.
Benefit/cost analysis usually uses money as a measure of utility, and thus monetizing benefits and costs is an important aspect of such an analysis.
