> In 50 years the generation of teens and 20-something will be eager for the deaths of the unrepentantly backward, greedy and immoral Gen Z.

More like millennials probably. Millennials are the second largest generational cohort after boomers, so will have massive electoral heft once the boomers shed their mortal coil.

Gen Z are probably going to be another Gen X type situation, always living in the shadow of their numerically larger predecessors.

Edit: Correction, millennials outnumber boomers as of 2019.
