I don't fully understand your comment, are you implying that older generations were able to buy a house in their 20s because they were loyal to their companies?
I wonder if the fact that we spend the last 50 years or so having policies erroding all our social benefits might have a role in the deterioration of overall living conditions.
But off course no, it's because our grandparents were more loyal to their companies.
Well, my family came up in a different country (not the US) and the two key things that enabled their rise from poverty were a literal obsession with working/putting in hours and entrepreneurship/"the hustle".
In my own life I have seen the enormous, overwhelming, and abundantly clear difference from when I self-commiserated, lamenting my own misfortune to embracing hardship, explicitly forbidding myself from whining, throwing myself into hard work, foregoing any kind of social life for a few years and eventually it all paid off, only getting better when I decided to be an entrepreneur.
But all my effort is nothing compared to the hard work my dad had to do, and even less compared to that of my grandfather's.
