Frightening thought, but this is the conclusion of an opinion piece in today's Wall Street Journal.
We just quote the sections on the economics of Obama's tax plan and its impact on productivity
The economics of what Sen. Obama is proposing should be at least as troubling. A high-income entrepreneur would see his or her federal marginal tax rate rise to 53% from 37.7% under Sen. Obama's tax plan. He proposes a 4.6 percentage point hike in the personal income tax rate, a loss of some itemized deductions, and a 12.4 percentage point hike in the Social Security payroll tax. This would take a successful entrepreneur's effective marginal tax rate higher than what it was under Jimmy Carter or Richard Nixon, when the maximum tax on an entrepreneur was 50%.
One of the lessons from the disastrous economics of the 1970s and the subsequent Reagan tax cuts is that everyone – particularly entrepreneurs – responds to incentives. If you take away 10% of a high earner's after-tax income at the margin, he will cut his taxable income by at least 4%. At the margin, this taxpayer now takes home 62.3% of his earnings, a figure that will drop to 47% under the Obama plan. According to a widely accepted economics rule of thumb, the entrepreneur's taxable profit would drop by 11.2%.
Now consider how the Obama plan would affect the taxes paid by such an entrepreneur with a taxable profit from his business of $500,000. Under current law, he would pay $27,148 in Social Security and Medicare taxes, plus $142,969 in personal income taxes, for a total of $170,117. If the taxpayer did not change his behavior at all, under the Obama plan he would face a $31,000 Social Security tax hike and a $11,494 hike in his personal taxes – or a 25% tax hike. But, if the taxpayer responds as the economic models predict, his taxable profit would drop to $444,000. His Social Security and Medicare tax bill would still soar to $51,580. But his income taxes, even with a higher tax rate, would drop to $132,882 for a total of $184,462.
In other words, Sen. Obama is planning on a combined series of tax hikes to produce $42,000 in tax revenue, but consensus economic modeling suggests the government's net take would rise only $14,000.
We should also keep in mind that the economic well-being of the country is not measured by how much taxes the government can collect, or even the size of the deficit. Rather, it is measured by the country's productive capacity. Our theoretical entrepreneur's 11.2% decline in taxable income reflects both less effort on his part and a less efficient use of his income in order to avoid confiscatory tax rates. Or, to put it directly, Sen. Obama's plan would reduce an entrepreneur's after-tax profits by $70,000 – $56,000 in lost profits and $14,000 more in taxes – just to produce a net revenue gain to the government of $14,000.
It is shocking to think that we have a presidential candidate who would make the private sector $5 poorer in order to make the government $1 richer. More likely, given the calculated political design of the proposal, no one in the Obama campaign told the candidate about the economic, ethical or historical consequences of his suggestion.
