Judas priest, I'd never thought that people were so out of touch with the rest of the world until I read this damn thread.
In the last year, I took a trip to Sudan for a relief project down there, and anyone there making $5 per day would be RICH compared to most of them. To put it in more Western terms, that'd be the guy driving the BMW. Not obscenely wealthy, but moreso than just about everyone else.
This guy is getting paid double the minimum wage. Again, for the pin-headed Americans who can't wrap their minds around this concept, that'd be about $14.50 an hour according the the current US-sanctioned minimum wage. That's pretty good money, I'd say.
How do people not understand relativity? If there was a country where the minimum wage was $20 per hour, and then came to an American and offered to pay him $14 per hour, are they exploiting the American? If it's for a job like the one mentioned, then no. A robotic, repetitive job for more than minimum wage is rare, even in the US.
OP, I'm willing to bet that gentleman is thankful that you're paying him almost double the minimum wage in his country, and you should be glad to have helped him feed his family and afford to live more easily than others in the country.
