Scarcity and Rationality

One common solution to Scarcity is rationing, e. g. during a water shortage.  Rationing, too, is what constitutes Supply-Demand Equilibrium, i. e. each side receives half of what it is seeking.  So, fair distribution can be characterized as 'rational'.  Accordingly, unfair distribution is 'irrational'.  Thus, Profit-Maximization, which seeks all take and no give, is irrational behavior, contrary to the standard characterization of it in Economic theories.  Instead, the aspect of a Capitalist system that does involve rational behavior is operating as part of a Division of Labor, i. e. in which roles are distributed on the basis of some organizing principle.
