Pitting generations against each other as if that's at all necessary is something the real elite, literally the old establishment is good at, because they were taught by millennia of that being the norm. Not only selfishness, it serves to make their kids become them.
Breaking through the false dichotomy of generations is itself a fundamental aspect of fighting against classist structures as a whole. 'Generationism' = classism, and those bs narratives need to be dismantled whenever, wherever.
Quite sneakily this is one of the toughest battles, bc it truly touches upon what your worldview over time. Which priorities you have, And our society has barely known anything other than rich people trying to stay rich because that 'serves the country as a whole'.
Liberals in particular are so blind to our society still being drenched in classism, some stemming from as far back as fucking feudalism. Capitalism isn't freedom, it adds a tier inbetween the disgustingly rich and the poor, dubbed "the middle class".
I mean how oblivious can you be, it's literally still called the middle CLASS, and justly so. Now that an 'old middle class' exists all this 'generationism' is meant for is to keep wealth from dispersing out of that middle class by distracting them w/ in-fighting.
