No other age cohort has been responsible for caring for the earth for the time they were adults and done such a horrific job. In the US, the cherry on top is also that this generation kicked everything their parents generation fought for into the dirt, including most of the social safety net, because of a bunch of dumb conservative rhetoric.
I think it is pretty fair as far as generalizations go, though of course it is a generalization. Boomers get all defensive with the “but you shouldn’t just blame a whole generation!” even though blaming millennials seems to be a major policy point for a lot of boomers… but they just don’t get it. The boomer generation will be remembered for literally thousands of years for being the generation that was adults in power when climate change was pushed into an unstoppable momentum, biodiversity catastrophically crashed, and the priceless gift of earth that has been handed down to every generation was dealt a massive amount of damage that will reverberate for again, literally thousands of years at the minimum.
Boomers think I am attacking them in an us vs. them mentality, it is unfortunately so much bigger than a petty fight between generations though. Boomers aren’t just another generation that will be largely forgotten a century or two from now, and it is a massive understatement to say the time they were stewards of the earth will not be remembered kindly by future generations.
