Nobody ever said that being president of the United States is an easy job. Whoever sits in that office has to juggle the competing demands and interests of various constituencies. The political tendency is for a president to make more promises to various societal sub-groups than he can actually do for them.
Underneath all the politicking, salesmanship, and maneuvering lies an inescapable reality: A president can’t be all things to all people. At some point, he needs to act praxeologically. Praxeology—literally, the study of human action—teaches us that the central act of being is the act of choosing between various possible alternatives. As the economist/praxeologist would say, humans choose that which (at the moment, at least) they value more over that which they value less.
