The reason for discussion is the amount of US-$ 6000 (or EUR 4800, as Marc Haber calculated).
For many of the readers that is really, really much money for just a month. Maybe it's even close to a yearly income in some other countries.
Many calculations and posts are dealing with living costs of Steve, costs of bureau rent, taxes, etc... but how about this calculation:
Now, who will get more work done within a month, when you have to give away 6000 US-$? 1 person or 30 persons?
Recalculate this with your average income of your country. Maybe Joachim Breitner can tell you, how much work can be done in Ghana for 6000 US-$ and how many people can make a living out of this?
So, you might guess it: I'm not very pleased about that high amount of money that is being spent for a single person. I think the money could've spent more efficiently.
