[Question] Is Modern Monetary Theory a good idea?

I don’t know very much about this, but it seems like MMT is getting enough cultural /​ political purchase that it could end up having a big impact.

Either a big positive impact or a big negative impact, depending on how sensible it is.

Does anyone with MMT expertise have a take?
