I really don't like the glibness of that sentiment, even if the idea is fine. As a voter or constituent, yeah, fight for Social Security, try to maintain it.
But as an investor? Recognize that your personal view has approximately no impact on whether Social Security exists unless you run for high office or devote your life to the topic. Make your best guess and save accordingly.
People shouldn't make their individual choices around the political views they support, because most individuals have virtually no influence on national outcomes.
