All I know is that it sure seems like the generation or two before me don’t drink anywhere near like what used to be. However, I think it did go up some during the Obama era judging by liquor store crowds.
Marxist leaders, killers, and exterminators are all the same and they do drive people to drink. The former USSR had the highest alcoholism rate in the world.
If available, you would have to look up the statistics, or counts, in the previous generations. I’m not sure they are available.
