There's a sense in which all taxes are antagonistic to free enterprise … and yet we need taxes. We have to recognize that we must not hope for a Utop… - Milton Friedman

The misuse of language contributes also to the belief that labor unions are a product of modern industrial development. They are nothing of the kind. On the contrary, they are a throwback to a preindustrial period, to the guilds that were the characteristic form of organization of both merchants and craftsmen in the cities and city-states that grew out of the feudal period. Indeed, the modern labor union can be traced back even further, nearly 2,500 years to an agreement reached among medical men in Greece.

Now, when anybody starts talking about this [an all-volunteer force] he immediately shifts language. My army is 'volunteer,' your army is 'professional,' and the enemy's army is 'mercenary.' All these three words mean exactly the same thing. I am a volunteer professor, I am a mercenary professor, and I am a professional professor. And all you people around here are mercenary professional people. And I trust you realize that. It's always a puzzle to me why people should think that the term 'mercenary' somehow has a negative connotation. I remind you of that wonderful quotation of Adam Smith when he said, 'You do not owe your daily bread to the benevolence of the baker, but to his proper regard for his own interest.' And this is much more broadly based. In fact, I think mercenary motives are among the least unattractive that we have.

Our gain from foreign trade is what we import. Exports are the price we pay to get imports. As Adam Smith saw so clearly, the citizens of a nation benefit from getting as large a volume of imports as possible in return for its exports, or equivalently, from exporting as little as possible to pay for its imports.
