How much inequality is a problem can be an opinion, but what we have is a trend to growing inequality.

At least that you are OK with total inequality (or with a systemic collapse) we should start to look at this carefully.

And this is what the article deal with, what is saying is: "the trend is going to reverse because it was born from demographics, nothing to do with the Washington Consensus, the dismantling of worker protections and other small details."
