> What's the difference between MMT & Keynes?

MMT seems to be 'always "print"' and then tax. Keynes is more about induce demand by government when it's needed:

> I would summarize the Keynesian view in terms of four points:

> 1. Economies sometimes produce much less than they could, and employ many fewer workers than they should, because there just isn’t enough spending. Such episodes can happen for a variety of reasons; the question is how to respond.

> 2. There are normally forces that tend to push the economy back toward full employment. But they work slowly; a hands-off policy toward depressed economies means accepting a long, unnecessary period of pain.

> 3. It is often possible to drastically shorten this period of pain and greatly reduce the human and financial losses by “printing money”, using the central bank’s power of currency creation to push interest rates down.

> 4. Sometimes, however, monetary policy loses its effectiveness, especially when rates are close to zero. In that case temporary deficit spending can provide a useful boost. And conversely, fiscal austerity in a depressed economy imposes large economic losses.

Now most governments run deficits in the modern world, and that is "fine" as long as borrowing costs/rates are lower than inflation and/or economic growth. And that you should generally be spending on things that helps raise productivity or induce economic growth.

Things like tax cuts generally don't do this:

Unfocused military 'forays' also tend not to do this.
