He shows that arguments to the effect that Jews were culturally preadapted to urban life and industrial occupations simply do not hold up to the facts: Jews were geographically segregated in the Pale and peripheral to such capitalist modernizing as there was in Russia; the economy in which they were enmeshed was a Jewish ethnic economy, not urban, and it was artisan rather than industrially based.
