No one doubts that one way for an individual to increase his wealth is by stealing other people’s stuff. But protectionism, as it is known, is not simply a misleading name for this truism. It is instead the idea that entire groups of individuals (e.g., Americans as a whole) can become more prosperous by raising the cost or depriving consumers entirely of the best deals otherwise available to them in the market. Get it? Having fewer or worse options improves the group’s situation.
