““In the half-century 1879–1929, Western societies developed into close-knit units, in which powerful disruptive strains were latent. The more immediate source of this development was the impaired self-regulation of market economy. Since society was made to conform to the needs of the market mechanism, imperfections in the functioning of that mechanism created cumulative strains in the body social. Impaired self-regulation was an effect of protectionism.””
