The Biggest Risk to the Economy in 2012, and What's the Economy For Anyway?

They also come at the expense of our Main Streets -- the hubs of our communities -- when we get the great deals through the Internet or at big-box retailers that scan the world for great deals on our behalf.

Some great deals have devastating environmental consequences. Technology allows us to efficiently buy low-priced items from poor nations with scant environmental standards, sometimes made in factories that spill toxic chemicals into water supplies or pollutants into the air. We shop for great deals in cars that spew carbon into the air and for airline tickets in jet planes that do even worse.

Other great deals offend common decency. We may get a great price or high return because a producer has cut costs by hiring children in South Asia or Africa who work twelve hours a day, seven days a week. Or by subjecting people to death-defying working conditions.

As workers or as citizens most of us would not intentionally choose these outcomes but as seekers after great deals we are indirectly responsible for them. Companies know that if they fail to offer us the best deals we will take our money elsewhere -- which we can do with ever-greater speed and efficiency.

The best means of balancing the demands of consumers and investors against those of workers and citizens has been through democratic institutions that shape and constrain markets.

Laws and rules offer some protection for jobs and wages, communities, and the environment. Although such rules are likely to be costly to us as consumers and investors because they stand in the way of the very best deals, they are intended to approximate what we as members of a society are willing to sacrifice for these other values.

But technologies for getting great deals are outpacing the capacities of democratic institutions to counterbalance them. For one thing, national rules intended to protect workers, communities, and the environment typically extend only to a nation's borders. Yet technologies for getting great deals enable buyers and investors to transcend borders with increasing ease, at the same time making it harder for nations to monitor or regulate such transactions.

For another, goals other than the best deals are less easily achieved within the confines of a single nation. The most obvious example is the environment, whose fragility is worldwide. In addition, corporations now routinely threaten to move jobs and businesses away from places that impose higher costs on them -- and therefore, indirectly, on their consumers and investors -- to more "business friendly" jurisdictions. The Internet and software have made companies sufficiently nimble to render such threats credible.

But the biggest problem is that corporate money is undermining democratic institutions in the name of better deals for consumers and investors. Campaign contributions, fleets of well-paid corporate lobbyists, and corporate-financed PR campaigns about public issues are overwhelming the capacities of Congress, state legislatures, regulatory agencies, and the courts to reflect the values of workers and citizens.

As a result, consumers and investors are doing increasingly well but job insecurity is on the rise, inequality is widening, communities are becoming less stable, and climate change is worsening. None of this is sustainable over the long term.

Blame global finance and worldwide corporations all you want. But save some blame for the insatiable consumers and investors inhabiting almost every one of us, who are entirely complicit. And blame our inability as workers and citizens to reclaim our democracy.
