The invisible hand
There are two important features of Smith's concept of the "invisible hand". First, Smith was not advocating a social policy (that people
should act in their own self interest), but rather was describing an observed economic reality (that people
do act in their own interest). Secondly, Smith was not claiming that
all self-interest has beneficial effects on the community. He did not argue that self-interest is always good; he merely argued against the view that self-interest is necessarily bad. It is worth noting that, upon his death, Smith left much of his personal wealth to
charity. On another level, though,
the "invisible hand" refers to the ability of the market to correct for seemingly disastrous situations with no intervention on the part of government or other organizations (although Smith did not, himself, use the term with this meaning in mind). For example, Smith says, if a product shortage were to occur, that product's price in the market would rise, creating incentive for its production and a reduction in its consumption, eventually curing the shortage. The increased competition among manufacturers and increased supply would also lower the price of the product to its production cost plus a small profit, the "natural price." Smith believed that while human motives are often selfish and greedy,
the competition in the free market would tend to benefit society as a whole anyway. This was later adopted as a universal principle by the
laissez-faire economists of the 19th century.
[edit] Meritocracy
Meritocracy is a strong theme in the work. Specifically, Smith stresses the critical importance of allowing individuals to achieve what their "God-given talents" will allow them to, without interference from outside forces seeking to shape larger societal outcomes. Smith posits that these outside forces lead to inefficiency in the division of labor and hamstring progress generally.
