Unmotivated Variables in Action

Pseudo-economists use variables in the formulas they create. This can’t be done. As Murray Rothbard pointed out, these variables are “unmotivated.” They can attempt to solve for the variable, but they can always change. In fact, everything in that equation is a motivated variable. It’s all uncertain and subject to change. The only constant in human action is change. The future will always be uncertain.
