It is common to think of capital as money, such as dollars invested in the stock market or in a business. Factories, office buildings, computers, tractors and trucks are all capital investments that increase the economy's ability to produce and distribute more and better goods and services to consumers at the lowest possible cost. The ultimate source of capital improvement is the human mind. America's greatest economic asset is our people. Knowledge is capital.
