The language in this article is filled with so much emotion and hyperbole - major red flags for bias- it’s hard to take it seriously. That being said mainstream economists don’t have a great track record when it comes to making predictions, the only problem is, neither do any alternatives. I am certainly no economist but the more I learn the more I think, just predict they’ll be wrong and you’ll probably do alright.
The writer said it himself, the logic of the paper really ticked him off.
