I can't speak for a generation, and probably wouldn't if I could. That said, I'm kind of sick of hearing about 30 year old shit myself. There were some fun times. You had to be there. There were some major fuckups. Best if you weren't there. It's done. Mostly, I just try to blend in.
Out of curiosity, what culture followed the boomers? More drugs? Even more massive consumerism, largely on credit cards? Remakes of 60's and 70's music? So what do the collective "you" want? Endless lines shuffling into and out of the Walmarts?
I suspect that society is an entropic process and that it's going to get less social until it finally breaks. The younger ones are going to pay for the older ones until the breakdown. And I suspect that they will all bitch about it. Paying, not the breakdown. After the breakdown, the younger ones will bitch about the older ones that trashed civilization. Obviously, I'm guessing.
As for your last point, I have been responsible about our retirement, and I don't think it's going to help. I expect to lose everything to the second major disease I get. The first will lose me my job and insurance, and the second one will wipe me out. Best to be dead by then. I'm not putting a lot of trust in the goodness of the next generations to keep this ponzi game going. YMMV.
