>It is actually truly revolutionary to disagree with it, e.g., take the stance that capitalism is an effective way of organizing labour.

Is this supposed to be satire? According to neoclassical economics, "capitalism" (to be precise, neoclassical economics actually denies the existence of capitalism) is a mathematically unimprovable system that is already as perfect as it gets and any alternative will make things worse. Economists are literally blind to the things that cause recessions and they will deny any potential solution because those are already assumed to be implemented implicitly.
