As South Korea shows, active participation in international trade does not require free trade. Indeed, had South Korea pursued free trade and not promoted infant industries, it would not have become a major trading nation. It would still be exporting raw materials (e.g., tungsten ore, fish, seaweed) or low-technology, low-price products (e.g., textiles, garments, wigs made with human hair) that used to be its main export items in the 1960s.

Self-interest, to be sure, is one of the most important, but we have many other motives - honesty, self-respect, altruism, love, sympathy, faith, sense of duty, solidarity, loyalty, public-spiritedness, patriotism, and so on - that are sometimes even more important than self-seeking as the driver of our behaviors.

Manufacturing is the most important...route to prosperity.

The foundation of economic development is the acquisition of more productive knowledge.

Democracy and markets are both fundamental building blocks for a decent society. But they clash at a fundamental level. We need to balance them.

In manufacturing, where mechanization and the use of chemical processes are much easier, it is easier to raise productivity than in services. In contrast, by their very nature, many service activities are inherently impervious to productivity increase without diluting the quality of the product.

It's not just about the current economic environment. History shows that slashing budgets always leads to recession.
