I guess this is my answer here, all I can do is look at the people in my immediate vicinity (I don't exactly live in a major city here, nor do I work in a white-collar field), and tell you that I am in no-way surprised by the outcomes of the polls here; and I also don't think that anybody that I know personally are substantially to the left (let alone more prone to organizing, probably less so tbh) than anybody in the Boomer generation was at our age; and a lot of the people I know don't even necessarily have their own home.

Perhaps geography, and proximity to the city has a larger impact on these things than intergenerational politics does. That's my perception of the matter.
