Trade can be believed to promote world peace as long as one assumes everyone has their price in terms of messes of pottage.
Reality is that this is not always true! And money itself is an amoral thing, a tool that can be used to do good or evil. And once actually idolized (a step in the spiritual dimension, into which economics can have no insight) it definitely becomes a root of all kinds of evils.
Wait, since when were we talking about love of money? Since when is free trade in closer contact with the evil which lurks in men’s hearts than protectionism? Certainly the political means of earning a living, i.e. stealing, is more prone to greedy exploitation than earning a living through trade.
Isn’t the point of this article that protectionism would materially benefit us? So it’s a technical question, not God against Mammon.
There is an un-nerving undercurrent of faith in the ability of bureaucrats to make things “fair” and “right” in your posts. We call that trait “liberalism.”
