Real wealth, of course, consists in what is produced and consumed: the food we eat, the clothes we wear, the houses we live in. - Henry Hazlitt

There is actually no limit to the amount of work to be done. Work creates work. What A produces constitutes the demand for what B produces.

The dilemma is this. In the modern world knowledge has been growing so fast and so enormously, in almost every field, that the probabilities are immensely against anybody, no matter how innately clever, being able to make a contribution in any one field unless he devotes all his time to it for years. If he tries to be the Rounded Universal Man, like Leonardo da Vinci, or to take all knowledge for his province, like Francis Bacon, he is most likely to become a mere dilettante and dabbler. But if he becomes too specialized, he is apt to become narrow and lopsided, ignorant on every subject but his own, and perhaps dull and sterile even on that because he lacks perspective and vision and has missed the cross-fertilization of ideas that can come from knowing something of other subjects.

The government spenders tell us, for example, that if the national income is $1,500 billion then federal taxes of $360 billion a year would mean that only 24 percent of the national income is being transferred from private purposes to public purposes. This is to talk as if the country were the same sort of unit of pooled resources as a huge corporation, and as if all that were involved were a mere bookkeeping transaction. The government spenders forget that they are taking the money from A in order to pay it to B. Or rather, they know this very well; but while they dilate upon all the benefits of the process to B, and all the wonderful things he will have which he would not have had if the money had not been transferred to him, they forget the effects of the transaction on A. B is seen; A is forgotten.
