I bought into that for a while (having followed that variety of economic opinion). The idea was that the whole system was hanging by a thread. A moderate shock would make it all fall over. Well, we got a hell of a shock in 2020, and we're doing economically kinda bad, as one would expect regardless after such a shock, but not catastrophically. I don't know what the right model is, but I no longer think that this is the one.
