Since the boomers are more conservative than the young and becoming even more conservative, then I do not expect the strongest Democrat voting blocks to suddenly sweep out liberal Democrat politicians and their agendas, so the only way that they could hurt boomers in the sense that you mean, would be for them to suddenly embrace conservatism, which is unlikely.
I do not agree with you that boomers are more conservative than the young. And especially not more conservative than the young will be when they get their first job and see 50% sliced out of their pay.
By “be kind” I’m talking about not wanting to be riding a bus with millineals when I’m 70.
