Since I started this... whether you want to call them Boomers or Jones, the point was the youngest are turning 60, which means we have another decade to go before the tail end of this biomass, that has had a finger on the scale since their birth, works its way out of the labor market and eventually economic system.
Anya was disagreeing with me saying real Boomers are turning 70.
The Jones sub-designation refers to cultural / sociological differences between the start and end of the biomass. The 1964 date is a well-established date, when you are doing what I am, talking about the volume of bodies. Employed bodies. Bodies that are functional to spend and travel. I guess the cultural definition would matter if there is evidence that it's only early Boomers who have been shoveling money to Disney all this time and the Joneses were doing other entertainment / vacation things.
