Pretty interesting. One thing that bothers me is "The way our economies are organised means wealth is increasingly and unfairly concentrated among a privileged few while millions of people are barely subsisting".

I don't fully understand "unfairly" in this context. According to the thefreedictionary this word means:

1. Contrary to justice or a sense of fairness 2. Contrary to laws or conventions, especially in commerce; unethical: unfair dealing. 3. Not kind or considerate: It was unfair of me to laugh when he felt so sad.

I am not sure I understand which of those description of unfairness applies to, say, Jeff Bezof (mentioned in the article). I have only limited knowledge about him, but I haven't heard that he had done anything that could be described as "unfair". One might even argue the opposite - he enabled many people to but cheaper goods in an easier way and he also enabled many people to sell goods efficiently and earn good money in this way.
