Why don’t they tell us the GNP anymore? When I was a kid, they always told us about GNP. We’d stand next to our dioramas (or is it diorami?) of SovietCollective Farms, or Asian rice paddies, and Mrs. Swallow (yes, actual name) would tell us about the GNP of the Soviet Union was such and such, or the GNP per person of whatever country we happened to be focusing on in Social Studies that week was higher than that of the social studies unit from last week.

Then sometime in the 90s GNP was quietly escorted off to some undisclosed location and mysteriously GDP appeared. “Does this have something to do with the metric system?” I wondered. No, it doesn’t. But it still was a bad idea. Here’s why: GDP doesn’t count the wealth which American businesses create in other countries. The D stands for ‘Domestic’ as in Gross DOMESTIC Product. If we make it here, GDP counts it. If we make it somewhere else, GDP doesn’t count it. For many countries, this doesn’t matter much. Their companies produce domestically.
