I see it rather differently. We are experiencing the crumbling of our infrastructure, military might, economy, democratic institutions, and cultural and technological advantages. People in their 20s will certainly not have the same standard of living or opportunities that older generations have had. Just because they still benefit from old glory and prosperity for the time being does not make them any less of a victim of current and future circumstances being a direct consequence of self-destructive policies adopted decades before these people were even born. Yet they will bear the brunt of the consequences.
By contrast, people in their 50s and 60s grew up in post-war prosperity and had the run of their lives. Even if their retirement is now endangered, none of that can take away the good life they have already had.
No to pick nits, but the "prosperity" I've had has been significantly diluted by an economic culture of "bubbles" wherein I've had the opportunity to see what
could be, just in time to have it stripped away in the next round of government meddling and foolishness.
I wonder if it can be called a "good life" to repeatedly live through financial catastrophes, accompanied by a steady increase in meddling and loss of liberties. Certainly, I've had my "moments," but I've had a disproportionate number of opportunities to look back and contemplate "how good it used to be" as the nation and my personal dominion has been methodically marginalized over decades.
The "good lifers" are actually in their seventies, eighties, or nineties, and even they have lived to see the demise of the prosperity they thought they had handed off to their heirs.
My son, in his twenties, has more than I ever had and, if he plays it cagey, may enjoy some prosperity of his own, but he can't lose what I lost, because he's never had it.
I pray he never has to reflect on the "loss of liberties" by comparison with what he has today.
