The term money has two very different meanings in popular discourse. We often speak of someone "making money," when we really mean that he or she is receiving an income. We do not mean that he or she has a printing press in the basement churning out greenbacked pieces of paper. In this use, money is a synonym for income or receipts; it refers to a flow, to income or receipts per week or per year. We also speak of someone's having money in his or her pocket or in a safe-deposit box or on deposit at a bank. In that use, money refers to an asset, a component of one's total wealth. Put differently, the first use refers to an item on a profit-and-loss statement, the second to an item on a balance sheet

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.

Nobody spends somebody else’s money as carefully as he spends his own. Nobody uses somebody else’s resources as carefully as he uses his own. So if you want efficiency and effectiveness, if you want knowledge to be properly utilized, you have to do it through the means of private property.
