“need is not demand. Effective economic demand requires not merely need but corresponding purchasing power.”

“The art of economics consists in looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups.”

“Mere inflation-that is, the mere issuance of more money, with the consequence of higher wages and prices-may look like the creation of more demand. But in terms of the actual production and exchange of real things it is not.”

“It is often sadly remarked that the bad economists present their errors to the public better than the good economists present their truths. It is often complained that demagogues can be more plausible in putting forward economic nonsense from the platform than the honest men who try to show what is wrong with it. But the basic reason for this ought not to be mysterious. The reason is that the demagogues and bad economists are presenting half-truths. They are speaking only of the immediate effect of a proposed policy or its effect upon a single group. As far as they go they may often be right. In these cases the answer consists in showing that the proposed policy would also have longer and less desirable effects, or that it could benefit one group only at the expense of all other groups. The answer consists in supplementing and correcting the half-truth with the other half. But to consider all the chief effects of a proposed course on everybody often requires a long, complicated, and dull chain of reasoning. Most of the audience finds this chain of reasoning difficult to follow and soon becomes bored and inattentive. The bad economists rationalize this intellectual debility and laziness by assuring the audience that it need not even attempt to follow the reasoning or judge it on its merits because it is only "classicism" or "laissez faire" or "capitalist apologetics" or whatever other term of abuse may happen to strike them as effective.”

“Necessary policemen, firemen, street cleaners, health officers, judges, legislators and executives perform productive services as important as those of anyone in private industry. They make it possible for private industry to function in an atmosphere of law, order, freedom and peace. But their justification consists in the utility of their services. It does not consist in the "purchasing power" they possess by virtue of being on the public payroll.”

“For every dollar that is spent on the (boondoggle) bridge a dollar will be taken away from taxpayers. If the bridge costs $1,000,000 the taxpayers will lose $1,000, 000. They will have that much taken away from them which they would otherwise have spent on the things they needed most.”

“The only way we could remember would be by constant re-reading, for knowledge unused tends to drop out of mind. Knowledge used does not need to be remembered; practice forms habits and habits make memory unnecessary. The rule is nothing; the application is everything.”
