I'm not enjoying being in the first generation to be poorer than my parents'. This is not a distraction; it's a big fucking deal.
My parents, personally, have not really contributed to the problem. They vote sensibly, they have been climate conscious (especially my dad) for wayy longer than most people. But those are individual stories amongst the overall picture.
On the wider point, being on the picket lines fighting for workers' rights doesn't have much bearing on whether you then voted to take money out of the public services your parents created, which you benefited from, so that you could enrich yourself personally.
I think you might have a slight fuzziness in your history here, too. The labour movement, at least in my country, reached its peak in the first decades of the 20th century. Boomers were born around the 50s, reaching adulthood around the 70s. We already had a minimum wage, 8 hour days, weekends, paid holiday, sick leave, etcetera. We already had a welfare system. Around this time, the "post-war economic consensus" was being dismantled, and public services were being sold off to private investors. If we're just looking at the resolution of generations, the prototypical grandma wasn't doing the things you're talking about - they were done by her mother or grandma or others.
Again, this is a broad brush with room for variation within generations. But there's a section of the online left that wants to remove all responsibility for anything, especially climate change, from ordinary people. As if we can but do the bidding of billionaires. But if a population votes for climate change, or votes to dismantle public services, they deserve the blame.
