“Whatever people do in the market economy, is the execution of their own plans. In this sense every human action means planning,” Mises wrote in Socialism: An Economic and Sociological Analysis.
“What those calling themselves planners advocate is not the substitution of planned action for letting things go. It is the substitution of the planner’s own plan for the plans of his fellow-men. The planner is a potential dictator who wants to deprive all other people of the power to plan and act according to their own plans. He aims at one thing only: the exclusive absolute pre-eminence of his own plan.”
