what were pros and cons from this paragraph: Adam Smith, a Scot and a philosopher who lived from 1723 to 1790, is considered the founder of modern economics. In Smith's time, philosophy was an all-encompassing study of human society in addition to an inquiry into the nature and meaning of existence. Deep examination of the world of business affairs led Smith to the conclusion that collectively the individuals in society, each acting in his or her own self-interest, manage to produce and purchase the goods and services that they as a society require. He called the mechanism by which this self-regulation occurs “the invisible hand,” in his groundbreaking book, The Wealth of Nations, published in 1776, the year of America's Declaration of Independence.

While Smith couldn't prove the existence of this “hand” (it was, after all, invisible) he presented many instances of its working in society. Essentially, the butcher, the baker, and the candlestick maker individually go about their business. Each produces the amount of meat, bread, and candlesticks he judges to be correct. Each buys the amount of meat, bread, and candlesticks that his household needs. And all of this happens without their consulting one another or without all the king's men telling them how much to produce. In other words, it's the free market economy in action.

In making this discovery, Smith founded what is known as classical economics. The key doctrine of classical economics is that a laissez-faire attitude by government toward the marketplace will allow the “invisible hand” to guide everyone in their economic endeavors, create the greatest good for the greatest number of people, and generate economic growth. Smith also delved into the dynamics of the labor market, wealth accumulation, and productivity growth. His work gave generations of economists plenty to think about and expand upon.
