But Afghanistan was a bitterly poor country whose people lived a self-sufficient subsistence based on farming and herding, in contrast to largely urban society in Iraq.
Many French Polynesians left their villages for urban areas, causing the previous era's self-sufficient subsistence economy to shift to a wage-based system.
The same processes instigated a shift from a self-sufficient subsistence economy to one based on wages, which in turn caused high rates of unemployment.
In other words, the number of hectares per family is only sufficient for subsistence agriculture, so families produce crafts to have income.
In the highlands, divided into a number of mutually contrasting environments no one of which could have provided sufficient resources for the subsistence of a single settlement, villages were presumably linked to each other symbiotically.
He noted properly that Pope John Paul II in Centesimus Annus, issued in 1991, called on governments to ensure wages sufficient not only for subsistence but sufficient to support a family and even ensure some savings.
