I agree, except for the lack of Western toilets it looks a great deal like my dorm room from the mid eighties.
These workers where making about $650 a month and only paying about $23 a month for room and board.
So in all reality in a country like China where the average monthly wage is less than $400 a month they where making a killing and getting to keep a vast majority of their pay.
If it was not paying high enough wages, why where there so many people willing to work for such low pay?
Exactly. For the average worker in this place, they don't face income tax. These people (all young) basically don't have lots of skills or experience, and they also don't expect this to be a long-term career. They do it for a few years, and go back home with enough money to buy a decent apartment, start a family or start a small business. Unlike in the USA, they aren't allowed to be a burden on society or their parents.
Its called climbing the economic ladder.
