And who do you think exactly contributed to the over financialization of everything? Every single thing, good or bad, is a direct result of the actions of the generation before. We can thank them for creating a world where women get to vote but also criticize them for creating a world where everything costs a million dollars and all young people can earn is pennies. At any point in time they could’ve been like “this may not in my selfish interest, but it will ensure the future generations can have the same life as i do” and pushed for policies accordingly. But that didn’t happen.
I understand the desire to find an entity or group of people to blame, but they were acting in their own self interest at a peak time, they didn't know the party would be over soon, for many of them, it still isn't.
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.
