That's the question I always ask when viewing the gerontocracy.
In academia at least it's been very clear that the boomers were shameless about working long past the time they should retire, preventing gen Xers from rising to top positions.
Apathetic? Maybe. But even if we were all on the same page as a group (which we're not) I don't see how we have the numbers to force a systemic turnover on our own.
I am, of course, a member of GenX. Sometimes, as Planck said, progress has to happen one funeral at a time. None of this brings me any joy to observe.
I don't like the GOP for many reasons (maga) and I think the current iteration of Democrats are horrifically inept with economics to a degree where they are a net harm for the people they strive to help. Belief in policies such as rent control is as anti-science as creationism.
Most Americans have fallen into the trap of lesser of two evils to a point where they don't hold their chosen side accountable at all and the result is predictable. Incredibly dysfunctional policy.
