First, a word about which time frame to use when describing this expansion. According to the National Bureau of Economic Analysis, the trough of the last recession occurred in November 2001. However, the Bush administration has repeatedly used the spring of 2003 as the starting point of the expansion for the simple reason this is when their second wave of tax cuts was implemented. The Republicans slavish devotion to the mantra of "tax cuts pay for themselves" requires them to move goalposts whenever it suits their political ends.

However, there are several reasons why using the Republican’s measure is wrong. First, the Republicans completely forget they passed tax cuts in 2001 which failed to provide the panacea they promised. The bill started cutting tax rates in 2002 – not 2003 as many commenters have claimed. In fact, tax revenues decreased after the passage of this bill from $994.3 billion in 2001 to $793.7 billion in 2003.

In addition, the Republican argument that their tax cuts are completely responsible for post 2003 growth completely ignores the impact of interest rate policy in the national economy. As this chart shows:

The Fed started cutting the Fed Funds rate in 2001, lowering it near 0% by the end of 2001. Standard economic analysis gives interest rate cuts a lag time of 12-18 months. That means these cuts had their maximum impact in the Spring of 2003 when the economy started to really take-off.

But finally, let’s look at the "explosion in tax revenue" the Republicans claim their tax cuts generate. Here is a chart from the St. Louis Federal Reserve which shows the year-over-year percent change in tax receipts. Notice that in the 1980s and 2000s there is no meaningful difference in the percentage change in tax receipts when compared to non – supply – side policy years. In other words, supply-side tax cuts don’t provide a meaningful difference in tax receipts when compared to non-supply side years.

Now that I’ve spent far too much time debunking the latest Republican lies about the economy (one of the joys of living in a talk radio fact free world), let’s move on to the reason this is the worst economy of a generation.

At the center of this issue is the incredibly weak job growth of this expansion. Here is a chart that breaks down job growth of the last 5 expansions into a per month figure. Notice that this expansion has the worst record by far.

Here are two other charts from the Big Picture which show the weakness of job growth.

This chart shows the percent growth of jobs for months 29-78 of the last four business expansions. This is the range of months where we are currently in the latest cycle.

This chart shows job growth in the last business cycles that lasted at least as long as the one we are in now.

The bottom line is clear – this expansion ranks last in job creation by a wide margin.

And weak job growth has lead to weak wage growth. Here is a chart from the Census Bureau that shows real median wage growth for the last 25 years. Notice that median income is down for this expansion.

Let’s stop right here because at this point we have a lot of information that explains public concern about the economy. First, the economy just isn’t creating that many jobs when compared to other expansions. That leads to factor number two – declining median family income. When you put those two factors together you get unhappy people. Jobs aren’t as plentiful as they were in previous expansions and people aren’t getting raises. That alone is enough to cause widespread discontent. This is why this "greatest story never told" (according to Larry Kudlow) polls so poorly with people. The Republicans are convinced they need better PR. But their PR doesn’t stack up to what people are seeing on the ground around them and in their bank accounts. And no amount of PR is going to turn that situation around.
