Taxes do not fund government spending.
That’s a core insight of Modern Monetary Theory (MMT) whose radical implications have not been understood very well by the left. Indeed, it’s not well understood at all, and most people who have heard or read it somewhere breeze right past it, and fall back to the taxes-for-spending paradigm that is the sticky common wisdom of the left and right.1
This, despite the fact that the truth of the proposition is obvious if you think through just a few steps about the process of money-creation. What makes it hard to see is the dense knot of conventional theory and discourse in which we are entangled, and which seems impossible to cut as cleanly as MMT suggests.
But the discussion around the newly-enacted Republican tax bill has brought the issue of tax policy to the forefront again, and it’s time for the left to realize how fundamentally wrong that common wisdom is, and how continuing to argue within the phony terms of the taxes-for-revenue paradigm occludes and reproduces a persistent reactionary fiction regarding what taxes are for.
