I have never seen sleepy used that way before.
I did a quick run of the numbers and it is rather hard to tell what the average hourly rate ìs. But it look a like if you went for four 40 hour weeks to get 320 it seems to be a little below the average pay for a call center operator.
In one sense this is a story of someone feeling bad about being paid to do something wrong.
It is not quite so simple when the reason why this happens is the income differential between countries makes it possible for people to be paid enough to put aside their ethics. That becomes easier when the processes is normalised so that they are not the only person making the same compromise.
Adding to the complexity of the situation is the fact that paying people like this puts money into the their economies and that can spur regional development to provide a higher pay level all round, causing the ethically dubious work to become less attractive.
In the very long term the only way to avoid the higher power of foreign weather from doing this is to balance incomes around the world. That requires accepting that the current wealthy countries cannot get cheap things by paying poorer people low wages, and that means having less for themselves.
