Note as well that Iceland, like all Nordic countries, has a very robust and generous social welfare state and social safety net. That clearly contributes to their relatively low level of poverty and desperation compared to the USA. And they are generally one of the most progressive countries in the world in that regard. And more so now than they were before the 2008 financial crisis. So that might also have something to do with it as well.
Another gem from the same article, about when the less-controverisal aspects of the Icelandic model have been tried in some other places with a drinking age of 18 and no curfew laws, as Kaunas, Lithuania:
Thus, when viewed through a more nuanced lens than the mainstream media does, it becomes clear that Iceland's apparently miracle can indeed be achieved without raising the drinking age (or smoking age) any higher than 18, and without implementing youth curfew laws either. Or any other forms of "social cleansing" for that matter, something the USA has a rather dark history of doing.
It's time for the USA to stop "chasing the dragon" of failed drug and alcohol policies, pun intended, because try as we may, we all know that we're never gonna catch it.
