The generation of our parents was obscenely materially overclass compared to their real social class — that is the one we got when the brief overclass phenomenon ended. To the point that some can't even accept there are still social classes in society, and you don't integrate the bourgeoisie by having jobs, even well-paid jobs. So it's our generation's fault if we are not all millionaires. We are broadly seen as failures by most of our parents, and the best ones are just telling us bitterly it's someway okay to be a failure. No generational thinking.
As you said, they wanted more and more, and they found it difficult to accept that sometimes, there will be an end. Accepting it would allow them to see their offspring as the prolongation of their lives. It would have made things very different for lots of families.
But the generation spiritual gap is too wide. And generation Z was thinking they would manage all this far better than our generation. They are just starting to understand society sold them fake dreams too and to realize that genX and baby-boom generations were bullshiting about us. There is one social burden less on our shoulders.
The main difference between the previous generations and us is that Millenials are looking to start things in their life, not to avoid end. We don't seek immortality, we want society to let us start our lives. GenY was the less psychologically impacted by the covid. We see a lot of cerebral damage in other generations, though. We are the first minimalist generation of the capitalist era, and we are happy when we just manage to have something for some length of time. Having something at all is already a privilege to our generation : we can't understand the thanatophobia of our parents, because our only fear is to die before having lived.
