So look at the places where drugs are legal or where drug law enforcement is very lax. They are no worse off - mostly better off - than our inner cities where drug gangs fight over turf.
When was the last time someone was murdered over a vineyard or brewery?
I've been to Amsterdam. It's completely degraded. I wouldn't want to spend my life fighting my way down a city block filled with druggies just to buy groceries. I assume the Netherlands subsidizes these folks with free health care, free food, etc. Except in the third world, I don't know where the land you're talking about exists.
