However.
I don't care how much it hurts to be canceled, or how ponderous your student loans are, or how sad you are that you can't afford a house. Shortly before my own lifetime, my parents worried about being ruined for good when an industry moved out of our Midwestern town. They wondered how they would literally eat if that were to happen. Where could they go? What could they do? Even in the midst of current uncertainties, these worries are laughably remote for almost everyone not on the far tail of the socioeconomic distribution, a membership that includes far fewer people than ever before in history. I volunteered at a homeless shelter during peak COVID. The state of those homeless folks, vs the state of my family from the rural Midwest a few decades earlier, would be unfathomable to those who had not personally witnessed both.
Progress is real. That it doesn't _feel_ real for some is exactly my point.
I think appealing to the past generations being "a tougher breed" to undermine the current concerns of now is a weak argument. A lot of people were just told to shut up and know their place or literally die.
I think life or death -- the prospect of starving or being homeless without recourse from relations or from society -- is different from the prospect of being stressed for other reasons. That people mistake more benign stressors for "life or death" these days is the hypothesis I am proffering.
And while I expect that you intend it as a dunk, I'll grant the point unreservedly: I very much _do_ think people were tougher in previous eras. When I read about the lives of our predecessors, and what they endured and how they bore up under it, I feel disgusted with myself. They were not perfect moral gods, but tougher? Jesus, yes.
When I look back at history I am more disgusted with the rampant exploitation that occurred, which made lives harder, an issue yet to be solved in the modern era. Sure people survived, but living a hard life is nothing anyone should aspire to, nor a reason society should be telling someone to "suck it up and stop whining".
