Some elements of the generation before. It's is exceedingly unhelpful the blame an entire generation for the actions of a few. There were some elite people with a plan, many more who bought the propaganda they were served, and a lot who had nothing to do with any of it.
Also, it's worth noting (to help build empathy) that you and me likely have been suckered by propaganda for things that the next generation will curse us for, but we just think we're being sensible and informed.
The least you could do is blame an ideological faction of that generation (e.g. neoliberals), rather than blaming the whole generation itself. Among many advantages, that names the problem in a way that can solve it.
The unfortunate reality is that every generation has the power to change things if they want to. Shifting the blame to the actions of the few is an easy way to absolve yourself of the blame. Who allows the few to take those actions? How did those few come into power to be able to take those actions? Once the actions were taken, why were they not corrected if the entire generation disagreed with them?
Maybe in the future the generations will blame my generation for a bunch of wrongs, even if I personally may not have contributed to those wrongs, I will still share the burden of not doing enough to prevent it.
That's an illusion. I think what you're really doing is putting unreasonable demands on the entire baby boomer generation, then blaming them for not succeeding at an impossible task. I mean, seriously, you really think, say, some boomer factory worker in Ohio is to blame for not foreseeing the effects of some 1980-era policy on 2026 or even 2006? They didn't have the benefit of the hindsight that we have.
It sounds like you're really holding tight onto blame, but what good does that do you? It solves no problems, and at best, alienates people from you.
