Link: Race replacement is not ok. However, there is a widespread belief in the fungibility of man, aka homo economicus. Absolute baloney, but economists kind of believe it. And this is what has been trotted out here.
Though they also kind of do not, when comparative advantage examples are used in the classroom. E.g. the US has absolute advantage over Mexico in everything, but Mexico has comparative advantage in T shirts. Why? Does the use of Spanish make it impossible to design a computer? Does frequent consumption of burritos make it hard to design the A bomb? So Economists recognize that there maybe something at work here but they refuse to delve deeper.
