I completely agree with this. A person did put in the same effort as the other one for learning something. Since a person leaves in an area which isn't properly developed or cheaper, he/she is living in order to save money or due to some other personal reasons, shouldn't be discriminated and paid less for the same talent/value the company receives. Obviously it always feels better to live in developed areas. When a company is receiving same quality from different vendors, they should pay the same for different vendors irrespective of their origin of locations.
