As you can see, the 10-year impact is $314 billion, mostly due to lower tax receipts, though there is some impact on outlays because of higher interest costs and a bit of additional entitlement spending.
So why am I sharing these numbers? Because let’s now think about President Obama’s proposed class-warfare tax hike. He wants higher tax rates on investors, entrepreneurs, small business owners and other “rich” taxpayers. And he wants more double taxation of dividends and capital gains. And a higher death tax rate, even higher than the ones imposed by France and Venezuela.
I think some opponents are exaggerating when they claim that this tax hike will cause a recession and cripple the economy. But I do think that it’s reasonable to contemplate the degree to which the Obama tax hikes will slow growth. More than 1/10th of 1 percent? Less than that? Would the damage occur in the first few years? Would it be spread out over time?
Those questions are hard to answer. Ask five economists and you’ll get nine answers, but there is compelling evidence that higher tax rates do have a negative impact.
But some people assume that taxes don’t matter at all. Using models that, for all intents and purposes, naively assume a simplistic linear relationship between tax rates and tax revenue, the number-crunching bureaucrats in Washington estimate that Obama’s proposed tax hikes will generate about $800 billion over 10 years.
I’m not going to pretend I know the economic impact of those higher tax rates, but for the sake of argument, let’s assume that the impact is minor. Indeed, let’s assume that it’s only 1/10th of 1 percent. Based on the CBO sensitivity analysis above, that means that about 40 percent of the projected deficit reduction will fail to materialize.
And that’s not even considering the fact that politicians will probably increase the burden of government spending because of the expectation of additional tax revenue.
Just something to keep in mind as this debate unfolds.
P.S. I actually shared this exact same data when testifying to the Senate Budget Committee earlier this year. Needless to say, in some cases I think my testimony went in one ear and out the other.
P.P.S. The revenue-maximizing tax rate is not the ideal point on the Laffer Curve.
