The arguments for state insurance extended beyond mere social equity. First, state insurance could step in where private insurers feared to tread. Second, universal and sometimes compulsory membership removed the need for expensive advertising and sales campaigns. Third, as one leading authority observed in the 1930s, ‘the larger numbers combined should form more stable averages for the statistical experience’.31 State insurance exploited economies of scale, in other words; so why not make it as comprehensive as possible?
