Russ compared a very talented person in Nepal to a lazy untalented teenage babysitter. The teenager made spectacularly more than a high skill individual. His theory was that the number of people the Nepalese could trade with was much smaller than Americans. Because of this, there is limited opportunity for specialization of trade in Nepal. The wages cannot be bid up, since there is not enough trade to specialize. Wages are dependent on productivity, and not specializing will make you relatively unproductive.
Bitcoin making trade easier, will help to bring wages closer together by allowing specilization. There are still a lot of other barriers to trade, but money transfer is one that bitcoin would help with.

Couldn't get the image of Arthur Dent and a perfectly normal beast sandwich making monopoly out of my head at the start of the first one. However, he went on to make some very good points but didn't discuss the implications of them (it wasn't the point of the article to do so).
Specialization raises productivity and so the standard of living. He does cover the effect of this in one part, there are only one set of skills required by each person so other skills decline. Taken further it requires people to only have specific skills, in effect it requires people to act more like machines. An education system geared to that result is a scary thought.
As better systems evolve to further increase productivity then each individual can produce more and more. I lived in France for a while and suffered French bureaucracy regularly. Taking a step back from that bureaucracy and seeing how it has continued to increase all the way through the digital revolution which should have made it obsolete its apparent that the only reason it still exists is to provide employment and so keep everyone within the economic system. We've already refined production to a high enough state that the entire world could have a high standard of living with only a fraction of the labour. The majority of the work done today is to support the economic system because it's the foundation of modern society, we've out-evolved it but society as we know it would collapse without it.
Another aspect is productivity could continue to evolve more freely and so provide more new areas for labour to diversify into but is being restricted by anti-competitive practices such as monopolies selling at a loss to restrict competition or the patent system being used to restrict innovation and preventing future technology being built on existing foundations.
Sorry, going off on a rant there. His analysis ended up considering things on a global scale with everyone entitled to compete equally and that's exactly what the communication age has given us.
Bingo.
And that is a problem with society as a whole, and not with the currency system.
