>The repeal of Glass-Steagall? I've read a lot of bad takes about the latter's supposed outcomes, but none of them claimed that the outcome was unpredictable.

>The repeal of Glass-Steagall? I've read a lot of bad takes about the latter's supposed outcomes, but none of them claimed that the outcome was unpredictable. It depends on what you mean by 'outcome.' If by outcome you mean that with GLBA/Glass-Steagall repeal banks began investing in the products they had previously been barred from then sure that was predictable. If we mean second order effects like it's possible contribution to the financial crisis then I'd say that was definitely unpredictable considering economists still can't agree on whether GLBA played a role or not.
