Dierdre N. McCloskey

Two centuries ago the world’s economy stood at the present level of Chad or Bangladesh. In those good old days of 1800...the average human consumed in modern-day prices...roughly $3 a day, give or take a dollar or two...The only people much better off than the $3 average were lords or bishops or some few of the merchants. It had been this way for all of history, and for that matter all of pre-history. With her $3, the typical denizen of the earth could eat a few pounds of potatoes, a little milk, very occasionally a scrap of meat. A wool shawl. A year or two of elementary education, if exceptionally lucky. At birth she had a 50-50 chance of dying before she was 30 years old. Perhaps she was a cheerful sort, and was "happy" with illiteracy, disease, superstition, periodic starvation, and lack of prospects. After all, she had her family and faith and community, which interfered with every choice she made. But anyway she was desperately poor, and narrowly limited in human scope. (pp. 11-12)

> [Today] the world supports more than six-and-a-half times more people...the average person today earns and consumes almost ten times more goods and services than in 1800. Real income per person in the world has recently been doubling every generation, and is accelerating. Starvation worldwide therefore is at an all-time low, and falling. Literacy and life expectancy are at all-time highs, and rising. Liberty is spreading. Slavery is retreating, as is a patriarchy enslaving of women. In the richer countries, such as Norway, the average person earns fully 45 times more than in 1800, a startling $137 a day. The environment - a concern of a well-to-do bourgeoisie - is in such rich places improving. (pp. 11-12)

# Interdependence

> “In civilized society [man] stands at all times in need of the cooperation and assistance of great multitudes, while his whole life is scarce sufficient to gain the friendship of a few persons...man has almost constant occasion for the help of his brethren, and it is in vain for him to expect it from their benevolence only,” (Book I, Chapter 2.2)

# Our Confined Generosity

David Hume

1711-1776

> “Men being naturally selfish, or endowed only with a confined generosity, they are not easily induced to perform any action for the interest of strangers, except with a view to some reciprocal advantage, which they had no hope of obtaining but by such a performance,” (Book III, Part II, `$\S$` V)

# Specialization and Exchange

Adam Smith

1723-1790
]
]

> “Whoever offers to another a bargain of any kind, proposes to do this. .hi[Give me that which I want, and you shall have this which you want]...and it is in this manner that we obtain from one another the far greater part of those good offices which we stand in need of. .hi[It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest.],” (Book I, Chapter 2.2)

> “[Though] he intends only his own gain, and he is in this, as in many other cases, .hi[led by an invisible hand to promote an end which was no part of his intention]....hi[By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it],” (Book IV, Chapter 2.9)

# Interdependence, “Globalization,” and Trade

- Cooperation through exchange is more prevalent than competition

- Trade within and between societies has been the lifeblood of civilizations
   - goods, services, people, capital, ideas, ideologies, religions, technologies, peace

- “Globalization” is not a new idea
