Most people are referring to the fact that boomers were born into the strongest social safety net in American history and then allowed Regan to gut it for short-term gains. The original aphorism may not be true, but I can’t think of a generation it applies to more.
Whenever people say that you grow more conservative when you get older, they’re working from the premise that you’ll grow more affluent and comfortable later in life. For Americans, that just isn’t true anymore. Wages are mostly stagnant, home ownership is much less attainable, and cost of living is at an all time high. Yet for some reason, pundits just can’t figure out why millenials aren’t getting more conservative as they age, or why zoomers appear to be following this trend.
