I actually agree with you and millennials are, rightfully, somewhat bitter about it. It’s not just post-war benefits. It was the era of 9-5 jobs, pensions, union jobs that paid nearly 6 figures in rural America…in the 90s…with no education, fully paid medical benefits for the family, and cheap homes.
What do we have now? Self managed 401k which you have pour a life savings and second mortgage into in order to beat inflation, overpopulated suburbs, record levels of pollution, rising temperatures, impossibly expensive homes, their kids getting shot in schools, their rights being stripped away, skyrocketing college tuition costs…
I actually believe a lot of millennials don’t know how bad they have it comparatively and somewhat ironically, boomers also don’t know how good they had it.
