First. Obama, along with most Americans in his age group (like my parents) are often considered part of a “gap generation” (because generational cohorts are a stupid idea with little validity). While technically boomers (cause identifiable, statistical population boom). Too young to have experienced the defining cultural elements of boomers as a whole. But too old to have experience the prime Gen X years while still young, sexy and responsibilityless.
Second. You’re forgetting the massive amount of ink wasted on how awful Gen X was back in the late 80’s and Early 90’s. And ignoring the large number of certified Gen Xers slinging massive bullshit about Millennials. Even as a middle schooler hearing about how Gen Xers were lazy, shiftless, and destroying America with their inability to care about anything it made zero sense.
It’s just even more pointless now. Since the whole “millennial” concept is so meaningless, and people have been bitching about them for 20+ years now. I mean seriously. People are writing insane “kids these days” articles about near 40 year olds with children, homes, and careers at this point.
