Seriously, if you're rich enough maybe what you say is true, but I don't think you could say "people’s daily lives have gotten as good as they’re gonna get" until poor people in "developed countries" don't have to worry about basic necessities to stay alive.
Perhaps one could strike a couple countries off the "developed countries" list and call it a day, but that list would be much smaller..
