I disagree that there's a fallacy at play here. The GP (GGP) should support their bold claim that "times have changed" and "people/teams aren't the same as they used to be." If anything, that's an extremely common fallacy and is not to be believed without sufficient evidence.
Actually, that's a fairly typical thing to say to someone that's older, and has lived through those times.
And I am sorry. Things definitely used to be better than they are now, in some ways, and definitely used to be worse, in other ways (for example, it used to be a very white, very male demographic). It's not my fault that things went the way they did. Folks liked money, so folks built a culture that maximized profit, and eschewed humanity.
I am quite sorry about that, but it doesn't change the fact that it was not always so.
It's not in my personal interest to go about creating a slideshow on "how things used to be." I know what I know. I lived it. I ran teams, exactly like I described, and I was a proud member of very large, high-functioning teams that stuck together for decades without stabbing each other in the back.
I don't disbelieve you, but I'm saying your experience can't be generalized in that way. Only aggregate data can tell us these things. Your experience may well have followed the exact trajectory you've described, but maybe 90% of people see the opposite.
