It's hard to understand why people choose to put others in these conditions. For example, who makes the decision not to pay overtime and why? It will save one dollar and thirteen cents an hour. What could this possibly amount to, in the cost of a Kindle?

Perhaps this is due entirely to the race to bottom inspired by competitive pressure -- the various bidders all trying to find a way to offer Amazon the lowest bid -- or perhaps it is due to internal pressures, where managers can be rewarded for finding savings that are significant relative to the cost of a certain phase in the process, even if it is of little consequence for the cost of the final device.
