Lawrence Lindsey explains in language even a numerophobe can understand precisely why Obama’s Social Security proposal isn’t just mean-spirted, pandering and illogical, but is also disastrous for the American economy:
Although the formula connecting benefits to tax payments or “contributions” has evolved slightly over time, it still adheres to this basic message. Today, what Social Security terms a “low-wage” worker will pay (in present value terms) $77,197 over his or her lifetime and get $112,261 in benefits. A median-wage worker earning $42,000 will pay $171,550 and get back $187,085. A “high-wage” worker making $67,000 will pay $274,480 and get back $245,085.
Under the current formula, lower-wage workers get a slightly better deal than do higher-wage workers, assuming the same life expectancy. But the principle remains that as workers’ wages rise so do the taxes they pay, and so do the benefits they will get from the system.
Sen. Obama would do away with this principle by requiring higher-end workers to pay taxes without getting any extra benefits linked to their higher contributions. This would be a big step toward turning Social Security from a contributory pension scheme into just another welfare program.
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%.
And that’s not all. Read the rest here.
