J.D. Foster and Curtis Dubay, writing at The Foundry (“Of Course Higher Taxes Slow Growth — A Response to Diamond and Saez“), make mincemeat of Peter Diamond and Emmanuel Saez’s arguments for higher taxes on “the rich.” Implicit in Foster and Dubay’s takedown of Diamond and Saez is the demonstrably strong (and negative relationship) between government spending and economic growth.
Spending is funded by taxes, after all. And even when spending is funded by borrowing it amounts to a tax on the productive sectors of the economy. How is that? When government sell bonds to the public it redirects money from productive uses in the private sector to unproductive and counter-productive uses in the so-called public sector (i.e., government). The thievery is no less destructive — but more apparent — when the Fed creates money out of thin air to finance government spending.
So, the focus should be on spending, for which taxation is a proxy. The effect of government spending on economic growth is nothing less than disastrous. I have treated the subject at length in “Estimating the Rahn Curve: Or, How Government Inhibits Economic Growth.” Here is another version of the final graph in that post:
The bottom line is that for every 10 percentage points by which government spending rises, the rate of growth declines by 0.7 percentage points. If you think that 0.7 percent is negligible, try compounding it over a lifespan of 80 years. In that time, a sustained 10 percent rise in government spending will reduce the average person’s real income by more than 40 percent.
That, my friends, is soak-the-rich Obamanomics at work. Apologists for Obamanomics, like Diamond and Saez, should be ashamed of themselves for abetting economically destructive demagoguery.
