In 1927, responding to the seemingly overpowering claims of advertisers and mass marketers, engineer Frederick Schlink and economist Stuart Chase published Your Money's Worth, which argued for an "extension of the principle of buying goods according to impartial scientific tests rather than according to the fanfare and triumphs of higher salesmanship." Your Money's Worth became an instant best-seller, and the authors organized Consumers' Research, a testing bureau that provided information and published product tests in a new magazine, Consumers' Research Bulletin. The 1929 stock market crash heightened suspicion of consumer capitalism, and the magazine had 42,000 subscribers by 1932. In 1933, Schlink and Arthur Kallet (executive secretary of Consumers' Research) published 100,000,000 Guinea Pigs: Dangers in Everyday Foods, Drugs, and Cosmetics. The book struck a responsive chord in depression-era America--it went through thirteen printings in its first six months and became one of the best-selling books of the decade. The book's first chapter ("The Great American Guinea Pig"), gave a flavor of their vigorous arguments.

What is the difference between a liberty and a right? Both words appear in the Declaration of Independence and the Bill of Rights.

The Declaration of Independence was a product of the Second Continental Congress. Two earlier intercolonial conferences had occurred, each building important keystones of colonial unity. The Stamp Act Congress and the First Continental Congress brought the delegates from differing colonies to agreement on a message to send to the king. Each successive Congress brought greater participation. Each time the representatives met, they were more accustomed to compromise. As times grew more desperate, the people at home became more and more willing to trust their national leaders.

Japan's location just off the fringe of continental Asia made it an ideal place for its unique culture to develop. The islands are situated close enough to China and Korea to benefit from the cultural and technological innovations of those great civilizations, but far enough removed across perilous seas to resist significant political and military domination from the two powers.
