As a boomer in the autumn of life, Neil Macdonald is mostly positive about the legacy of his own cohort, even as he feels the breath of self-important millennials on his neck. The boomer metric for a life well-lived has always been social progress writ large. Macdonald calls his generation the "engine" of the welfare state and the rainbow coalition, and also the moving force for averting a third world war. But there is something of la vie en rose at work here, for it was the parents of the boomers who pioneered these advances in the postwar world—and who made the greatest personal sacrifices to see them through. Macdonald is right about one thing. It is a bummer to live long enough to see one's own irrelevance.
