So you seem to agree that 2020 and 1920 look very different, as far as the environment that people found themselves in. You seem to take issue with my claim that things have not improved for the better. Lets agree here instead that that some aspects of the environment are better and others are worse.

Going back to the subject at hand (fentanyl use), I think one can safely state that more people are dying from drug overdoses and suicide than they were in other decades in US history. Is it people who have changed, or their environment? And do you disagree that there is a correlation? Certainly there has to be. Availability of fentanyl correlates with fentanyl deaths, whereas unavailability of fentanyl would correlate with lack of fentanyl deaths. And so all the ways that the environment of 2020 is now better than in 1920, seems not to translate to less drug overdoses and suicides. And I can think of no better indicator of quality of life, than the indicator of how many people are choosing death over living.
