At each step, there are none of the sudden leaps in assumed knowledge that I've found in other instruction books.

Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people’s lives as never before. The pessimists who dominate public discourse insist that we will soon reach a turning point and things will start to get worse.
