The video falls apart in some around midpoint. Like he discusses redistribution like it's an exclusively good thing since the money can be used to pay more debt, but doesn't account for the productivity reductions this entails will just makes total debt even worse. Also he seems to say the only problem with stimulus is that it increases government debt, but again it reduces productivity so much that it makes total debt even worse. Fiscal austerity also isn't net negative. It doesn't decrease productivity.
