The government can harness land, labours and capital to serve the economic objectives of the state. Consumer demand can be restrained in favor of greater capital investment for economic development in a desired pattern. In international comparisons, state-socialist nations compared favorably with capitalist nations in health indicators such as infant mortality and life expectancy, although the statistics concerning infant mortality are self-reported and based on varying standards. The state can begin building a heavy industry at once in an underdeveloped economy without waiting years for capital to accumulate through the expansion of light industry and without reliance on external financing. This is what happened in the Soviet Union during the 1930s when the government forced the share of gross national income dedicated to private consumption from eighty percent to fifty percent. As a result, the Soviet Union experienced massive growth in heavy industry, with a concurrent massive contraction of its agricultural sector, in both relative and absolute terms.
