The GDP Today: How Down Becomes Up
If the chief of your local police department were to announce today that "activity" on the city streets had increased by 15 percent, people would not be impressed, reporters least of all. They would demand specifics. Exactly what increased?Tree planting or burglaries? Volunteerism or muggings? Car wrecks or neighborly acts of kindness?
The mere quantity of activity, taken alone, says virtually nothing about whether life on the streets is getting better or worse. The economy is the same way. "Less" or "more" means very little unless you know of what. Yet somehow the GDPmanages to induce a kind of collective stupor in which such basic questions rarely get asked.
By itself the GDP tells very little. Simply a measure of total output (the dollar value of finished goods and services), it assumes that everything produced is by definition "goods." It does not distinguish between costs and benefits, between productive and destructive activities, or between sustainable and unsustainable ones. The nation's central measure of well being works like a calculating machine that adds but cannot subtract. It treats everything that happens in the market as a gain for humanity, while ignoring everything that happens outside the realm of monetized exchange, regardless of the importance to well-being.
By the curious standard of the GDP, the nation's economic hero is a terminal cancer patient who is going through a costly divorce. The happiest event is an earthquake or a hurricane. The most desirable habitat is a multibillion-dollar Superfund site. All these add to the GDP, because they cause money to change hands. It is as if a business kept a balance sheet by merely adding up all "transactions," without distinguishing between income and expenses, or between assets and liabilities.
