From Reason comes the tale of David Strange, the generator man, bringing electricity to people in the wake of ice storms in Kentucky:
Strange drove the hills and hollows of backwoods Kentucky delivering
and setting up generators to those without power—at a $50 to $100
mark-up over retail. Willing customers included a dialysis patient and
a powerless 80-year-old woman dependent on an oxygen system. They
called him a "godsend," although Strange prefers "jack of all trades"
or even "hustler." To Adam Smith, he would be recognizable as an agent
of the invisible hand.
