last stand implies they're on the losing end of things
Boomers have ruled this world to their exclusive benefit and get to retire in luxury with a pumped up stock market that will come crashing down after they've cashed out their investments.
Never mind the mess they've made of the environment and the way they've always told themselves "we will be dead when this is a problem, let the kids clean it up"
Boomers were among the most radical generation of the 20th century and did the back-breaking spadework in countless social, political and environmental movements. Pigshit-ignorant brats whose awareness of the past doesn't stretch any further back than the last game they played are among the most cynical, selfish, vapid, and apathetic specimens of any generation.
