I don't know if I'm missing the mark or not, but I definitely feel the relative "wealth" in the west is a tremendous benefit. Wealth in this case being the (typically) high availability of food, water, and shelter. I imagine in many other locales, the work required to obtain these necessities is much greater, thereby leaving an equally smaller amount of free time available for practice. Granted, there are many more distractions and overt attempts to draw us into the material culture, but discipline coupled with mindfulness can deal with that. There isn't much that mental effort can do if you have to spend the whole day struggling for food, water, etc.
