The Jewish community in Palestine enjoyed enormous advantages over the Palestinians in the industrial sphere. These advantages included capital in the form of financial contributions from Jewish communities overseas, highly skilled manpower in the form of professional Jewish immigration into the country, and industrial plants made available not only through access to industrial capital but also because restrictions prevailing in Germany allowed Jewish capitalists wishing to settle in Palestine to transfer their assets in kind only. Other factors favoring the Jewish community in the industrial sphere were its class structure (largely urban middle-class), its centralized political institutions, and British protectionism. Thus in every field of industrial endeavor, the Jewish community predominated. But Palestinian traditional industries (particularly the production of edible oil and the manufacture of soap) were vigorous, and Palestinians were increasingly active in the tobacco, textile, wood products, cement, and paper industries.
