These are the minimum wages which you mentioned.
It means that majority of the people will be earning much more than that. I do agree that it has something to do with the developed and underdeveloped nations and the currency conversion value with respect to dollars.
Maybe not for the locals but if any foreigner from developed country visit there, then he can buy the entertainment for cheap.
No, they do not. In reality they earn much more lesser amount than that. If you ever go to those countries then you will see how many homeless sleeps on the predestine area, railway station, parks and other places.
Even in first world, I wonder how many people get paid by the minimum wages? People who works for cash in hand, in some cases they ends up getting half of the legal hour rate.
Not sure which country you are from but I have friends and family through out the Europe/United Kingdom, I do visit there often. I hang up with some of the community and what I am saying is pretty much true for that community.
Those who are smart and do not work for money they actually making good money.
