I'm skeptical about this catching on, but I hope something replaces GDP. It's used everywhere, and treated as gospel by the media and politicians, but it's absolutely terrible.

Consider the broken window fallacy. It's Econ 101 that you don't gain anything by breaking a window just to create work for the glazer, window installer, etc. Yet, if I went around breaking all the windows in my neighborhood, GDP would increase! This is actually a pervasive problem with the measure. Consider polluting activities. A coal plant that creates tremendous air pollution contributes doubly to GDP. First, the activity itself contributes to GDP. Second, the health damage created by the pollution creates work for doctors, etc, which also contributes to GDP! If you replaced the coal plant with a wind power plant that cost the same, but didn't create any health damage, GDP would actually go down, even though it's quite obvious that the economy is better served by the latter.

The degree of reverence with which the media and political system treats GDP is completely ridiculous given how stupid the measure really is.
