It is customary in many families to give thanks to the hands that prepared this feast during the Thanksgiving dinner blessing. Perhaps we should also be thankful for the millions of other hands that helped get the dinner to the table: the grocer who sold us the turkey, the truck driver who delivered it to the store, and the farmer who raised it all contributed to our Thanksgiving dinner because our economic system rewards them. That’s the real lesson of Thanksgiving. The economic incentives provided by private competitive markets where people are left free to make their own choices make bountiful feasts possible.
Happy Thanksgiving everyone!
