In this 1990 essay, famed economist James S. Henry gives a surprisingly detailed point-by-point on why he hates Christmas, which he equates with "primitive Keynesianism":
According to the U.S. Postal Service, the volume of mail traffic more than doubles to 220 million letters and 6 million parcels per day the week before Christmas, battering a system already weakened by tens of millions of catalogs and advertisements during the previous two months. Telephone calls reach as high as 131 million per day in the month from Thanksgiving to New Year's Eve, according to AT&T. At many stores and post offices, there are long lines, and costly second and third shifts have to be added to handle them, which consumers ultimately pay for. All of this "peak loading'' at Christmas means that airlines, mail delivery, stores, banks, warehouses, telephone systems, roads, and parking lots must be built much larger than if activities were distributed more evenly throughout the year. That wastes precious capital.
