Another point I might add: Please factor in the rate of unemployment and the limited choices for labor when measuring the happiness of these "unskilled" workers.

I agree that we can learn a lesson of efficiency from these guys, but I don't agree that we can learn a lesson of cooperative society and sharing of dividends.

Lack of exposure means we rationalize the existing situation and convince ourselves that this is good. I'm sure there are some dabbawalas thinking "It is what it is. There are no other jobs available, so I might as well."
