>>>If people are living such wretched lives that the oblivion of alcohol or heroin addicition are seen as preferable alternatives
That has ALWAYS been the case and you will never change it.
I just watched "Who do you think you are" about Alan Carr and his great grandad was in India in the Army in the mid 1850s.
It was mind numbingly boring and the only way to relieve the boredom was to get drunk.
Drunkedness was a huge preblem and his grandad was busted down to private for drunkedness.
If you look back through history many people have drunk to excess. The Salvation Army campaigned against it, the Cadbury family (quakers) sold drinking chocolate as an alternative to drink, there was Gin (mothers ruin) the cause of many women becoming prostitutes to pay for the gin.
I am not saying it is right, but all through history people drank to get through the daily grind.
My first wife, an unhappy woman, drank herself to death, and she was dead before she was 50.
