This is a serious problem, all right, and it requires a serious solution. I propose a new Federal law that limits total U.S. Christmas light power consumption to no more than, say, the average power output of North Korea. It’s the only reasonable thing to do.
To make things fair, I suggest the new law allocate via a Christmas light lottery. Every U.S. household gets to enter the lottery a single time for a 100-light-string equivalent. Winners can choose to use their allocation for an indoor tree or for exterior decoration, but not both. Losers are nominally just chit out of luck. However, winners will be allowed to resell their allocation at whatever price they choose. This gives the losers SOME hope that they too might still have a chance at Christmas lighting. However, no one will be allowed to possess more than a single allocation, because otherwise those evil rich people are likely to end up with an unfair amount of Christmas lighting. You know, because they are rich. And evil.
