OK, so let's instead start with some facts: Please Register or Log in to view the hidden image! That's age vs number of people at that age. Note the end of the bulge,.... this data was 2008. You'll notice a steady INCREASE in population (with one spike) up to the age 40, when things start to decline. So what does this mean? That businesses geared up and catered for that peak demographic,... so when I was twenty, still the peak demographic, there were lots of businesses targetting my demographic, same when I was 30, same now I'm 43. What does this mean in reality? Well, one, there are fewer 20 year olds than 40 year olds, but if you were in the pub trade, and had a lot of pubs and bars to cater for all of my demographic, when we were pubbing every Friday and Saturday, and your market moves on, and shrinks, what you gonna do? You have fewer customers, but the same overhead... the law of elastic sales comes into play; Please Register or Log in to view the hidden image! to create the same revenue, you have two choices,... charge more,.. or shift more product, so guess what they did? They made boozing a bit cheaper. More offers, more happy hours, generally kept prices as affordable as possible, so they shifted more product. But that means drunk customers. Thanks to globalisation, offshoring, and imports, the cost of living went down, giving younger people more disposable cash, so more were able to afford nights out drinking. Lastly, opening times changed. When I was in my 20's, night clubs closed at 02:00hrs. Now, pubs can open until then, nightclubs even later. We had a choice, go home when the pub closed at 23:00hrs, (22:30 when I first moved to the City I went to college at!) or PAY to go to a nightclub. But if you can stay in a pub drinking, you can spend that admission fee formerly spent on night club entry on yet more booze instead. So guess what? Nightclubs lower entry fees, and do more promotions on booze. A nightclub locally had a promotion for lager at £1 a pint. That's late 80's prices, same as when I was in my 20's, but with earnings suitably higher now. So simply, people over indulge, because they have the means, motive, and opportunity. These things have eached subtly increased, and hence the binge culture. It's absolutely bugger all to do with drink driving.
