If you are in another country/market, then we are very able to pay market salary and in most cases even above market salary, while providing a great work environment at the same time. We have and had people from Ireland, England, Germany, Spain, Italy, Brazil, Croatia, Serbia, Mauritius, Thailand, Azerbaijan, Austria, Thailand, Argentina and probably a couple more that I forgot now.
So basically what I wanted to say: just because we cannot afford a Silicon Valley market salary, doesn't mean we are underpaying people elsewhere or treating them unfair (financially speaking).
I hope my answer helped to clarify things.
