Well, the entire article is about how rich corporations are being threatened by newly created companies at poor(er) countries. With a subtle context about huge bureaucracies not being able to compete with smaller (but still big) more centralized ones.

If there is a problem of wealth accumulation (there is on my country - but I have no idea about the global situation), the worse thing one can do is describe the problem using outdated models that are known to give very incorrect solutions for this exact problem.

>but I do think we have a problem with capital accumulation by the very wealthy.

Correct.
