This theory has huge ramifications for U.S. policy toward population management (especially immigration policy) and trade. The implications for population policy may be obvious, but why trade? It’s because these effects of an excessive population density – rising unemployment and poverty – are actually imported when we attempt to engage in free trade in manufactured goods with a nation that is much more densely populated. Our economies combine. The work of manufacturing is spread evenly across the combined labor force. But, while the more densely populated nation gets free access to a healthy market, all we get in return is access to a market emaciated by over-crowding and low per capita consumption. The result is an automatic, irreversible trade deficit and loss of jobs, tantamount to economic suicide.

One need look no further than the U.S.’s trade data for proof of this effect. Using 2006 data, an in-depth analysis reveals that, of our top twenty per capita trade deficits in manufactured goods (the trade deficit divided by the population of the country in question), eighteen are with nations much more densely populated than our own. Even more revealing, if the nations of the world are divided equally around the median population density, the U.S. had a trade surplus in manufactured goods of $17 billion with the half of nations below the median population density. With the half above the median, we had a $480 billion deficit!

Our trade deficit with China is getting all of the attention these days. But, when expressed in per capita terms, our deficit with China in manufactured goods is rather unremarkable – nineteenth on the list. Our per capita deficit with other nations such as Japan, Germany, Mexico, Korea and others (all much more densely populated than the U.S.) is worse. In fact, our largest per capita trade deficit in manufactured goods is with Ireland, a nation twice as densely populated as the U.S. Our per capita deficit with Ireland is twenty-five times worse than China’s. My point is not that our deficit with China isn’t a problem, but rather that it’s exactly what we should have expected when we suddenly applied a trade policy that was a proven failure around the world to a country with one sixth of the world’s population.

If you‘re interested in learning more about this important new economic theory, then I invite you to visit my web site at OpenWindowPublishingCo.com where you can read the preface, join in the blog discussion and, of course, buy the book if you like. (It’s also available at Amazon.com.)

Please forgive me for the somewhat spammish nature of the previous paragraph, but I don’t know how else to inject this new theory into the discussion of economics without drawing attention to the book that explains the theory.
