I’ve explained before that one of the most damning pieces of evidence against Obamanomics is that the economy is suffering from sub-par growth, something that is particularly damning since normally one expects to see faster-than-average growth following an economic downturn.

In a recent presentation, Robert Lucas of the University of Chicago included a couple of graphs that illustrate this phenomenon. This first chart shows the history of U.S. economic growth over the past 140 years. As you can see, the growth rate was remarkably constant over time, and there were always periods of rapid growth following economic downturns.

Lucas, who won the Nobel Prize in economics in 1995, then looks at the data for the recent downturn and recovery. As you can see, we have been struggling to get back to average growth rates and we have not enjoyed any of the above-average growth that normally follows a recession.

The key question, of course, is why growth has been anemic, resulting in (what seems to be) a permanent loss of output. In his presentation, Lucas warns that bad government policy is playing a big role. He says that “the problem is government is doing too much,” and he specifically highlights the “likelihood of much higher taxes, focused on ‘the rich’” and a “large increase in the role of government” in the healthcare sector.

In his conclusion, Professor Lucas is not overly optimistic about recovering lost output. He doesn’t make any flamboyant claims, but he does note that “European economies have larger government role and 20-30% lower income level than US.”

The obvious connection, as I’ve pointed out on many occasions, is that America is becoming a European-style welfare state and it is unavoidable that we will suffer from European-style economic malaise.

P.S. It should be noted that America’s anemic economic performance in recent years is not solely Obama’s fault. As the White House repeatedly points out, he inherited a downturn. That is completely accurate. My complaint, however, is that Obama promised hope and change but instead has exacerbated the big government policies of his predecessor.
