The Boomer generation across the world threw down in Leftist revolutionary and anti-colonial struggle, too, and many of them are not as well-off as they age either.

You’re not wrong, but it isn’t purely a generational question. Younger generations are also already terribly lib, grind mindset oriented, and could very well get reactionary as it ages. Once all Boomers leave us, our problems won’t magically be resolved and we won’t have global Communism. Some of us may just not have parents around to witness the rise of the new elite class, that’s it.
