"" (p. 64) However, Smith's Law of Accumulation does account for the welfare of the misfortunate. The same self-interest that motivated the entrepreneurs to accumulate would cause them better working conditions in order to attract more workers and produce more, for example, raise wages, build factories, and buy machinery, which provides "that wonderful division of labor which multiplies man's productive energy."" (p. 64) This Law still does hold true in some respects; entrepreneurs do accumulate as much as possible, capital is reinvested into the companies so that the laborers do eventually benefit. Although, as with Smith's other three tenets, time has changed the Law of Accumulation's fine points. Entrepreneurs today accumulate such wealth that it is nearly impossible for all of it to get back to the laborers. Bill Gates for example, posses a wealth in the tens of billions of dollars. But Adam Smith could not have foreseen such wealth in future times, so this flaw must be excused. After excusing his error in being unable to predict billionaires, Adam Smith's Law of Accumulation, developed over two hundred, twenty-five years ago still holds true.
Another of Smith's doctrines, akin to the Law of Accumulation, is the Law of Population. This Law affects economics because it explains the relationship of the size of the workforce to wages and therefore retail prices. From an economic standpoint, this Law is reasonable because the workforce really does rise and fall with wages. Aside from the workforce, which at any given time is a finite amount, Smith accounts for the future workforce: children. Medical care, as it is any other commodity, is affected by wealth and economy. In eighteenth century England, child mortality rate was astonishingly high: "In many places in England, half the children lived only to the age of nine or ten."" (p. 65) As Smith figured, the amount of health care would rise with wages.
