Elder millennials are going to be the most politically engaged and relevant leadership cohort for the next 40 years. It’s because this pocket of millennials (1980-1987) remembers the before times vividly. Home ownership. Landlines. Car phones. Dial up internet. But also a hegemonic nation and normal American life before everything got weird. Younger generations didn’t experience it. And older generations took it for granted. They’ll dominate the left and the right for a simple reason: they remember.
