That article doesn't do anything to dispel my suspicions that he has no idea what he's talking about.
The most egregious aspects of the article were addressed in Jason Hickel's response to Milanovic. I think it's funny that he's citing a World Bank economist for a major chunk of his article given that the World Bank's position is that we can grow our way out of global poverty (it'll only take 200 more years!) and currently defines the threshold of extreme poverty at $770 per year, so it's a little bit hard to take the argument that $5,500 is unacceptable (even if that were the degrowth position, which it is not) with a straight face.

As far as the argument for decoupling goes, the evidence is that to the extent that it's happening, it isn't fast enough.
