Even if that were so, it's pretty obvious that the baby boomers influence of politics left the generations behind them with a lot of shit to clean up. Maybe it was because of ignorance, maybe it was because of pride and maybe even it was because of malice.
But honestly I think you'll find left and right and all-between millennials refusing to sympathize with the aging boomers who are demanding to be taken care of and demanding a standard quality of life, because those same folks over many decades steered society into a direction where "free-loaders" are considered scum.
I personally don't think it has to do with the direction of anyone's political leaning, the baby boomers were just greedy fucks.... that's about it.
