Things are certainly changing. My son lives in a flat of 5 male University engineering students in the UK. None of them drink much alcohol at all. They don't even drink tea or coffee. Very different from when I was at University in the 80s.
Some of those friends disappeared almost immediately. The only thing we really had in common, after all, was drinking together. But what was most notable was that, within a few short years, the vast majority of that group of friends was stone-cold sober.
I’m now in my mid-to-late 30s, and I don’t have a single friend who drinks anymore. My wife and I never started drinking again, and we’ve even seen some of our older family members stop drinking too.
At least in my anecdotal experience and within my bubble, it’s becoming increasingly normalised to be sober. When I quit drinking, people questioned the decision, asked me if I had a problem, and were generally quite hostile the idea. When my sister-in-law quit drinking last year however, people celebrated the decision.
Times are certainly changing.
Sidenote: the amount of money I have saved by not drinking is astounding. I mostly funnel anything I don't spend into index funds and the returns have been staggering.
