The magic money tree is permanent spending of the same invented money, it is not temporary – the effects are permanent – and it is not reversible without stinging tax rates. It is also known as the monetisation of fiscal policy, or the monetisation of spending. And it has everywhere and everywhen been a disaster from the point of view of subsequent inflation. Not inflation of a couple of percent here and there either, but of two and three digits a year sort of inflation.
There is also mention of the Hungarian pengő, which I understand to be a small and adorable penguin.
