Why Tax Increases Won’t Fix Our Budget ProblemsApril 13th, 2011 by Lee Eldridge
I’ve had a number of conversations recently about tax policy and our federal deficits. I have many friends who would have liked to have seen the Bush tax cuts expire on the rich. It was estimated that this would generate $700-800 billion over the next ten years, not including any economic repercussions from the tax increases. The math is pretty easy on this one. That’s $70-80 billion per year (we’ll pretend as if there are no economic effects from the tax increases). And with a projected deficit this year of approximately $1.65 trillion, that extra revenue from the increased taxes on the rich means we still have a $1.57 trillion deficit this year.
Matter of fact, if you increase the top tax bracket from 35% (the current marginal tax rate on the highest income earners) to 100%, you still cannot collect enough in tax revenues to run a balanced budget.
The math doesn’t work. You cannot increase taxes and solve our nation’s budget crisis. But that’s just part of the story.
As I mentioned in my last post, too often we ignore history. Too many people believe that tax rates determine tax revenues. They do not. Proof? How’s this:
This table shows the top marginal tax rates since the mid-’40s (the tax rate paid by the “rich”). Tax rates have been as high as 94%, and as low as 28%. And the table shows total tax revenues collected by the federal government as a percentage of GDP.
During this time, tax revenues have remained extremely stable as a percentage of GDP — varying from a low of 14.4% to a high of 20.6%. So no matter how high we have made the tax rates, or how low, we still have not collected much more than 20% of GDP. Ever.
Maybe the rich should pay a higher percentage than they do today to be “fair”. That’s a discussion for another day. The point today is that no matter what tax rate you pick, you don’t ever collect much more than 20% of GDP through taxes. And on average you collect less.
Why? That’s an easier answer than you might expect. Higher taxes are a disincentive to work. Let’s say we reverted to the tax rates of 1970, where the “rich” were paying a marginal rate of 71.75%. And let’s say you’re earning $250,000. For every extra dollar you earn, you have to pay almost 72 cents to the federal government. Then kick in a little more to your state government. Why would you waste your time earning more money? If you’re a small business, such as an S-corp or an LLC, and the company profits are reported on your personal taxes, why would you want to grow your business? What’s the incentive? It’s no longer money, because the government is taking almost every additional dollar of profit you make. Why would you create more jobs? Create new products? Once you hit $250k, it’s time to kick back and head to the beach. High tax rates kill productivity, creativity, and economic activity.
Do you know how big the federal government is compared to GDP? How about one more table (I almost excluded 1945 because the war spending made this a statistical outlier, though I found it interesting so I left it in):
This table shows total GDP in billions of dollars. And the percentage of GDP that was spent by the federal government. Think of it as the relative size of the government compared to the economy.
Historically the size of our government has been less than 20% of GDP until about 1970. From 1970 until the mid-’90s we were in the low 20s. It’s no coincidence that the last budget surplus we had seen was in 1969. It wasn’t until the mid-’90s when we restrained government spending that government expenditures fell below 20% of GDP. The result? Budget surpluses from 1998-2001.
Now let me state the obvious. If our government spends more than about 20% of GDP, we will have a budget deficit. If we spend less than 20% of GDP, there’s a good chance we’ll run a budget surplus.
How have we done the last couple of years?
2009: Government expenditures were 25% of GDP.
2010: Government expenditures were 23.8% of GDP.
2011 (estimated): Government expenditures will be 25.3% of GDP.
And in these three years alone we will have added approximately $4.35 trillion to our national debt.
Our government doesn’t have a tax revenue problem. It has a spending problem.
