The key to the creation is saving, and the saving is left up to the consumer. When people cut back on consumption to save and invest, they liberate factors of production to generate new capital. Yet this tactic is not always possible. In some countries, people are so impoverished that they cannot bear to save their money because it would compromise their survival. In these countries there is low investment in capital goods.
Labor is the third factor that influences economic growth.
A skilled and growing labor force within a nation allows its economy to grow. In general, the rule is, is that the size of a labor force is related to the size of the population. It the rate of population growth declines, so does the labor force growth rate. This is where foreign workers step in. New additions to the labor force help offset a labor shortage.
