The Consumer Problem
Martin Ford's structural observation that mass automation is self-defeating: when machines replace the workers who are also the customers, the demand that justified building what the machines produce evaporates—making unrestrained automation a threat not only to workers but to the market economy itself.
The consumer problem is
Martin Ford's most structurally original contribution, and the one that ought to persuade even committed capitalists who are indifferent to the distributional concerns of displaced workers. A consumer economy runs on a circular flow: firms pay wages, workers spend wages on goods and services, that spending becomes firms' revenue, revenue pays wages. This circuit has a dependency that Ford makes explicit: employment is not merely a cost to be minimized but the primary mechanism by which purchasing power is distributed broadly enough for the consumer economy to function. When a single firm automates its workforce, it reduces costs rationally; when every firm does the same, the aggregate effect is to drain wages from the system, and with them the purchasing power on which all the firms collectively depend. Each individual decision is rational; the collective outcome is self-defeating.
