They are more electable if they don't talk about this complicated economics, pretending that MMT does not exist.

Actually, MMT is much simpler to understand, which is why politicians and orthodox economists reject it. They hide behind the complexities and boring charts and graphs as they explain why they can't fulfill their Constitutional mandate to provide for the "common welfare" using the power of the purse they were given.

If it can be sourced it is affordable to a sovereign currency-issuing government. This means that "ALL" misery that can be mitigated with federal dollars is entirely a "political decision", not economics. Austerity politics should be rightly viewed as murder by proxy in the richest nation in world history.
