>Plenty of wealthy people and plenty of intelligent people have addiction problems. Wealth and intelligence are bad predictors of addiction. A far better predictor is family history.
Family history is strongly correlated with wealth and intelligence, though. [0]
Studies comprising "adults in Britain" consist almost exclusively of mostly relatively well-to-do and highly educated people, compared to the rest of the world. [1]
Britain basically controlled the world during the entirety of the 1800s. They're a lot better off than most still as a result of that extremely long reign.

And? What does that have to do with your original and wrong claim that wealth and / or intelligence lead people to be better at moderation when it comes to addictive substances?
> Studies comprising "adults in Britain" consist almost exclusively of mostly relatively well-to-do
Your claim was about wealthy. You are moving the goal posts from wealthy to "relatively well-to-do" and "compared to the rest of the world".
And that does not explain why Brits who drink coffee live longer than Brits who do not. Or why the very many studies outside the UK show the same results.
