Henry Charles Carey, an American economist and advocate of protectionist policies, challenged prevailing economic theories of his time with his emphasis on the importance of domestic industry and national development. His ideas, known as the American School of Economics, exerted a lasting influence on economic thought and policy in the United States.

"In this country protection has always, to some extent, existed; but at some times it has been efficient, and at others not; and our tendency toward freedom or slavery has always been in the direct ratio of its efficiency or inefficiency."



"Then it was that the exports of slaves from Virginia and the Carolinas was so great that the population of those States remained almost, if not quite stationary."



"As regards this country, in which protection has always to some extent existed, it is the best customer that England ever had, and our demands upon her grow most steadily and regularly under protection."

"In the period from 1824 to 1833, the tendency was steadily in the former direction, but it was only in the latter part of it that it was made really efficient."



"To enable men to exercise that power is the object of protection."



"In 1833, protection was abandoned, and a tariff was established by which it was provided that we should, in a few years, have a system of merely revenue duties."



"It will be said, however, that protection tends to destroy commerce, the civilizer of mankind. Directly the reverse, however, is the fact."
