I mean, I'd argue the "most ignored" is always the youngest. They're not always the quietest, they are definitely heard, but you can be heard and still ignored. It's unfortunately part of natural progression of life that as generations age they (generally) have more power to actually influence changes.
The main problem is that the boomers have been around and in control for so long they are refusing to start to cede power (and wealth) to the younger generations, and continue to serve their own interests. If the younger generations had property wealth and they had stock market wealth, you would see them (generally) supporting more of the activity associated with it. But because the older generations hoard and hold so tightly to that power and wealth, the influence of the "up-and-coming" generations is hamstrung by not being able to actually push for the changes they want from a position of strength.
So the younger generations lean towards the ideas that seek to eliminate that power source entirely, because clearly the "transfer of resources" is simply not happening. If you can't get in the door, then why even have the building, so to speak.
I think the better question is not "who is being ignored?" but rather "who is doing the ignoring?". Gen X, Millennials, Gen Z, are all generally aware of each other's struggles and have empathy (for the most part) for one another. But the boomers hear the struggles of all 3 of the others and go "pull your bootstraps, stop buying avocado toast, nobody wants to work" and continue to serve the interests that benefit them, not the other groups that need the benefits.
And yes there are exceptions, there are young people in power who stomp on other young(er) people but the political climate across each of the younger generations is generally pissed off "upward" because the path to get there is being actively hacked away at.
