How much is the minimum hourly wage in India? I think it's nearly non-exist; moreover, 743 yen equivalent to about 500 rupee is the monthly wage for most of the domestic help (per family for whom they work) or similar kinds of workers. That's a sad and miserable fact. 

On the other side, working in Japan as a worker who receive the minimum hourly wage standard is also depressing, in terms of the poor living standard compared with the higher side (but I won't say expensive, due to ever-lasting deflation that is pulling down the minimum wage eventually) of commodity prices. Additionally, the poor working environment can impact your mental health as people implicitly expect the best from you even if they pay you less.

Physical pressure and mental pressure, the earth for humans is already suffocating place to live, all caused by the fellow humans. What is the thought in your mind?
