If I may provide some help, economical theory has some explanations, including the Stopler Samuelson conclusion in the HO model for international commerce : in an economy focusing on the export of highly technical outputs, the best qualified have their "salary" go up, while the least qualified have their salary go down (leaving aside the fact that physical capital is responsible from most of the productivity gains, an explain Marx dislike since according to him it's all about how labor use and create physical capital)
You can get such a divergence if you have fewer qualified people than less qualified people. Wrong conclusion like the one mentioned in the blog post can be reached when using a representative agent approach, while the actual population follows an (at least) bimodal distribution.
In the end, there still is a divergence, but it doesn't have to be resolved - people either have to learn more and become more qualified and productive, accept their reducing wage, or move to another country (Mundell conclusion in the HO model IIRC)
There is no reason why someone should commend a higher salary than someone else, just for having won the birth lottery ie being born in a reach country. If someone from say India is more productive than me, I see no reason why I should get more money than them.
A free market would help out some here; maybe its the lack of a global free market that is causing the disparity. In which case, being born in the wrong place would definitely put you at a disadvantage.
