It is economical to quantize known trends

Equivalently, we set up production gains to get goodies passed out with the minimal effort.  I wonder if I can get the principle of WalMart Economy Theory down to three words:  We hate queues!
Congress has strongly recognizable tendencies, taxes to the center; goods to the periphery. I often point out the rank difference in distribution between South Carolina and California.  We bridge that difference with a rate machine.  We count out some extra goodies at smaller rates for SC, and crank out bigger chunks for CA less often. Add in the Midwest, we likely got quite a machine in the Senate.

Here is the point.  When the economy is especially constrained by an input then ultimately the mutual entropy between the constrained and unconstrained grows, they ship more thing synchronously over time, to overcome the constraint.

Under these constraints, it is very difficult for the machine to deliver small things to SC more often.  The incoherence with the constrained input causes problems at the short end of distribution, first, I think.   Government ultimately changes.
