I take your statement to be a bit tongue-in-cheek, but if you're unfamiliar with Strauss-Howe generational theory[0], you'd think there would be another "good generation" right around the corner.
While I do think we went kind of downhill since gen x, I wrote that comment as a joke.
You actually could argue that new generations are worse because we're lazier, hedonists, more disrespectful, etc or you could argue that boomers and gen x are actually the bad ones that left everything in such a bad state that following generations spent decades to make everything right again.
GenX will never be in power. There aren’t enough of us. They’ll just skip us and once the Boomers die off, we will be a handful of elderly kooks watching Seinfeld reruns and dealing with Millennials making all the rules for themselves.
