In brief, on net balance, machines, technological improvements, economies and efficiency do not throw men out of work. - Henry Hazlitt

Everything we get, outside of the free gifts of nature, must in some way be paid for.

There is a strange idea abroad, held by all monetary cranks, that credit is something a banker gives to a man. Credit, on the contrary, is something a man already has. He has it, perhaps, because he already has marketable assets of a greater cash value than the loan for which he is asking. Or he has it because his character and past record have earned it. He brings it into the bank with him. That is why the banker makes him the loan. The banker is not giving something for nothing.

What men do not know about they take for granted. Knowledge furnishes problems, and the discovery of problems itself constitutes an intellectual advance.
