What I'm talking about is slightly different than that.
This is more like alcohol apathy - not drinking, but also not explicitly anti-alcohol. That the more generational shift in Gen Z that I've seen. But, those sentiments can certainly change over time.
What I have noticed in the UK is:
1. health concerns mean moderate drinkers drink less, but heavy drinkers have not changed their habits 2. young people seem to go more to extremes: either drink a lot or be teetotal.
