主题：【原创】中国为什么那么多人有钱了就要找二奶? -- 大汉大家

Rapid population growth adversely affects every aspect of economic and social progress

in developing countries. It absorbs large amounts of resources needed for more productive

investment in development. It requires greater expenditures for health, education and other social

services, particularly in urban areas. It increases the dependency load per worker so that a high

fraction of the output of the productive age group is needed to support dependents. It reduces

family savings and domestic investment. It increases existing severe pressures on limited

agricultural land in countries where the world's "poverty problem" is concentrated. It creates a

need for use of large amounts of scarce foreign exchange for food imports (or the loss of food

surpluses for export). Finally, it intensifies the already severe unemployment and

underemployment problems of many developing countries where not enough productive jobs are

created to absorb the annual increments to the labor force.
