However, even if the senator is not prepared to embrace norms of civility, it is reasonable to expect that he will do his homework. In order to help him in this process, here is a quick list of study questions on Social Security for Simpson as he carries through his assignment to co-chair President Obama's deficit commission. Reporters and editors at major news outlets may also want to review these questions, since it seems that they could also use some additional background knowledge on the program.
1) How much higher are real wages projected to be in 2040 than today? In other words, how much richer do we expect the average worker to be 30 years from now?
2) How did the 2010 Trustees Report change the projections for 2040 wages compared with the 2009 report?
4) What percent of real wage gains over the last 30 years was absorbed by the increase in Social Security payroll taxes?
5) What percent of the projected long-term budget shortfall is due to the inefficiencies of the US health care system?
7) What percent of older workers have jobs in which they can reasonably be expected to work at into their late 60s?
Certainly anyone on the deficit commission should be able to answer these questions off the top of their heads, as should any of the people reporting on Social Security or deficits in the media. But for those readers who do not fit these descriptions, here are the answers.
1) According to the Social Security Trustees Report, the average real wage is projected to be 48.7 percent higher in 2040 than it is today. In other words, if our kids work 30-hour weeks on average, they would take home about 10 percent more than we do today working 40-hour weeks. Senator Simpson has been known to quip about how our children and grandchildren will be living in chicken coops, but he's just kidding, right?
As a practical matter, most workers have not seen much in the way of wage gains over the last three decades because such a large portion of wage growth has gone to those at the top: people like Senator Simpson and his co-chairman Erskine Bowles. This upward redistribution of income of this period, and the possibility that it could continue, is the reason that most people who are concerned about the well-being of future generations focus on the distribution of income. The impact of any potential increases in Social Security taxes on the typical worker's income is trivial compared to the impact of a continued upward redistribution of income.2) The 2010 Trustees Report had good news on the wage front. It assumed that health care reform would slow the rate of growth of employer provided health care benefits. This means that wages are now projected to grow more rapidly since Social Security money will be diverted to cover rising health care costs. In 2009, the trustees projected that the average wages would only rise by 37.2 percent between 2010 and 2040.
This means that the changes between the 2009 and 2010 Trustees Report imply that wages will be nearly 10 percent higher in 2040 than we previously believed. Everyone saw or heard the lead item in The Washington Post and on National Public Radio: "New Trustees Report Shows Our Children Will be Much Richer." O.K., maybe they managed to overlook this part of the story, but Senator Simpson knows it.
3) Number 3 is somewhat of a trick question, since it depends on exactly the formula we use. The Trustees Report tells us that if we raise the tax tomorrow by 0.96 percentage points on both the employee and employer (1.92 percent in total), then the program will be fully solvent through its 75-year projection period. If we went this route, then it would mean that the tax increase would take up 5.9 percent of the projected wage growth over the next three decades.
But we may not want to impose a tax increase like this tomorrow. There is a huge amount of uncertainty about these projections, and the program faces no imminent shortfall. Suppose we raised both side of the payroll tax by 0.07 percentage points annually beginning in 2020 and continuing at least to 2040. Then by 2040, the rate would have risen by 1.47 percentage points on both the worker and employer. This would take up 12.0 percent of the projected wage growth over this period, leaving our children on an after-tax basis just 42.8 percent richer than we are. This doesn't quite sound like Senator Simpson's story about our kids living in chicken coops.
4) The Social Security tax increases of the last 30 years took 6.8 percent of average wage growth. This is in the same range as the portion of projected future wage growth that may have to go to higher Social Security taxes. The big problem in the story is that people have been living longer through time. If we want to enjoy a growing portion of our lives in retirement, then it will cost somewhat more money. This means that after-tax wages will grow Social Security more rapidly than would otherwise be the case.
