Hey, I'd bet that you enjoy drinking, so it's quite likely that your friends also feel the same way. No surprise there.
"hanging out in the backstreets of some backpackers village..." Chances are that in places like that, most people LOVE to drink, and line up several deep at any of the (government run) "Wine Shops". They may well earn less than a dollar a day, but that won't stop them from getting their booze.
As to "nobody cares", I doubt you know very much about India, as in most things, India is just the opposite.
It doesn't really matter. There are more than enough web sites to give you an idea of the general "feel" about drinking in India, and you can come to whatever conclusions you want. I doubt drinking will be banned, but it gets more restricted all the time. Closing time for all the "Wine Shops" recently changed from 11pm to 10pm.
Maybe I'll take a photo of a typical "Wine Shop" and you can judge for yourself what it's like. (...and yes, the "Tourist Hotels" serve drinks that the tourists expect, at a price that mostly only tourists will spend...)
Of course, none of this has anything to do with the topic of this discussion, but is only in response to Faulty. All I was trying to say up above, was that at prices like 600 baht for a beer, it's no wonder that no locals would go there. ...and at prices like that, neither would I, vacation or no vacation.
