Conservative intellectuals, commentators, and politicians are rethinking the relationship between free enterprise and the common good. While critiques of the market have a long history in traditionalist circles, most American conservatives have held for several decades that protecting markets from government was essential for human flourishing. But that consensus is quickly changing as many elements of classical liberalism are now being challenged. The question is not whether to jettison free enterprise in favor of the common good, but rather how to orient free enterprise in support of the common good.(emphasis added) This requires properly understanding the common good and how free enterprise affects it. Conservatives must learn to treat hard-nosed economics and humane political economy as complements, not substitutes.
Right - that’s still a leftist bent. “Common good” is socialism.
Protectionism is an entirely different beast.
