I'm not sure I understand the large sentence in your last paragraph, and that seems to be what the final questions are related to. I'll answer them, but you'll have to clarify that paragraph for me.

People being jerks is one thing. With a neighbor like that, it makes sense to quit interacting with them, regardless of their generation.

The argument that I frequently see is "Boomers are taking my money because they want SS paymemts.", so that's the context I was flying under. Being bitter that they had better conditions is the second most common beef I see expressed, and it's rather pointless, and still not their doing.

Buying into the generational-war psyop pulls people away from basic logic while they get wrapped up in labels, and start pasting them around. It also creates a victim identity for both sides. The same energy could be used for better things.
