The Department of Labor cites Labor Day as “dedicated to the social and economic achievements of American workers,” adding that “it constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.” Celebrating the hard work of Americans with a yearly day off is fine with me, but there are additional forces contributing to the “strength, prosperity, and well-being of our country” also worthy of recognition. Perhaps the time as come, for instance, for a Capital Day.

Hard work is important. Americans have long considered a strong work ethic a virtuous quality, and this has been to our advantage. But hard workers are all over the world, and the US hardly leads the world in average hours worked. Yet America is consistently at or near the top in worker productivity. What accounts for this discrepancy? Simply put, capital.

Another way to look at American prosperity is this: hard work is a necessary, but insufficient, condition for achieving prosperity. Give even the hardest worker a spoon, and it will take a long time to build a ditch. Give that same worker a shovel, and it will take less time. Now give that worker an expensive digging machine and that ditch will be completed exponentially faster. That is where growth in worker productivity comes from.

The mixing of capital and labor is where the true magic happens, and American prosperity is due to our once unique devotion to an economic system – the free market – that most efficiently matches these two ingredients.  Unfortunately, America today is no longer the most devoted to economic freedom, and the trend is heading in the wrong direction. A less free economy, generally speaking, will mean more inefficient distributions of capital and labor, resulting in a less productive workforce and thus a less prosperous economy.

In order to invest capital in our workers, we first need capital to invest, and that means savings. Unfortunately, neo-Keynesian economic thought can be reasonably accurately summed up as “savings = bad; spending = good.” Just consider the examples of politicians asserting that unemployment checks or food stamps boost economic growth because the recipients are more likely to spend it.  And then there’s the many government policies which reduce or inhibit capital formations, like direct taxes on capital such as the capital gains tax or death taxes, financial regulations and laws which discourage US investment, and other costly burdens on business – such as Obamacare.

So while we celebrate the contributions of hard working Americans of all stripes, we should keep in mind the importance of capital in achieving prosperity, a fact all too often forgotten by policymakers. Perhaps a yearly reminder in the form of a Capital Day is needed to do the trick.
