Looking at all you have said here and using my home country as a case study. $1,500 times four equals $6000 ( a month) and going by it when converted to my local currency we will arrived at about #3,600.000.that runs into millions we are talking about here, that even those we describe as rich people here in my home country don't even earn half of such amount in their 5months salary put together.
So most definitely, even ten persons in a family will definitely live like a king in any West African countries earning such amount $6000 per month.
If the person have around 1000 - 2000 dollars than there so many countries where they can live like a king, Indonesia is definitely one of the countries - it is beautiful and standard of life are real good there. If I ever get a chance - I will move to Indonesia.
