The Tragedy of the Commons

In 1968 Garrett Hardin, a biologist, wrote a seminal paper in the journal Science entitled “The Tragedy of the Commons”. The “commons” in the title referred to the English village common land on which all village inhabitants could graze their cattle and sheep in common.  The point of the paper was to point out that the commons tended to get overgrazed because for any individual farmer, the entire profit from grazing one more cow or sheep went to that farmer, while the cost of overgrazing was spread among everyone in the village. So there was a clear incentive to overgraze.  This paper established the general principle of “privatizing the gains” while “socializing the losses”. A factory owner, for example, who spews waste products into the water or air, is privatizing his gains (by not spending potential profits on cleanup gear) while socializing his losses (spreading the contamination costs across everyone in the neighborhood).

Why do I bring this up?  Because at root the worldwide unrest reflected in this unusual election is driven by just this effect, and the political parties need to come to grips with it if they are to remain in power.

When a factory automates or moves production offshore to a lower wage market, it is privatizing the gains (It lowers production costs, so the shareholders and executives make more money) while socializing the losses (the whole community and all the taxpayers bear the costs of all the unemployed and displaced workers who lost their jobs).  In the American tradition of laissez-faire capitalism, the company can do as it pleases, and its only obligation is to its owners and shareholders.

What clearly has to change is that – probably by law, because what company would do this voluntarily – when a company automates or moves production offshore, some of the additional profit it makes from this change needs to be funneled back into effective help for those workers displaced  (“made redundant” as the English say) by the change.

This is more than just a moral argument, though it is that too.  It is a practical and pragmatic argument for three clear reasons:

1)      Our capitalist economy depends on having markets to sell products to.  Unemployed people with no income provide no market for goods. It is in the interests of everyone, but especially the businesses that produce goods, to have as large and as wealthy a potential market as possible for their goods.

2)      Americans can tolerate a fairly large disparity between those who are rich and those who are not, but there is a limit, and I think we are reaching it.  Stability in any nation depends on not having too large a proportion of disgruntled people.  This election is showing that that proportion is getting fairly large in this country, perhaps even large enough to elect a demagogue like Donald Trump.

3)      Unemployed people are wasted productivity and talent.  Economists have long pointed out that an hour of work lost can never be recovered – it is economic waste, and in an increasingly competitive world economy any nation that wastes talent by keeping some of its workers unemployed is reducing its competitiveness.

However this strange election ends, both political parties need to come to grips with this fundamental problem if they are to retain any long-term political leverage in the nation.
