From Friedrich List:
The power of producing wealth is therefore infinitely more important than wealth itself; it insures not only the possession and the increase of what has been gained, but also the replacement of what has been lost.
List is talking about power to create wealth at the national level. He has a much more nuanced view of free trade, as summarized in the introduction to the book:
In the first stage they [a developing nation] must adopt free trade with the more advanced nations as a means of raising themselves from a state of barbarism and of making advances in agriculture. In the second stage they must resort to commercial restrictions to promote the growth of manufactures, fisheries, navigation, and foreign trade. In the last stage, ‘after reaching the highest degree of wealth and power,’ they must gradually revert to the principle of free trade and of unrestricted competition in the home as well as in foreign markets, so that their agriculturists, manufacturers, and merchants may be preserved from indolence and stimulated to retain the supremacy which they have acquired.
