Take per capita real GDP. Give hostages by taking data from 1950 to 1980, which means including the 1980 recession, but stopping at 2007, so that the current slump isn’t included. Then here’s what you get:

Growth in per capita real GDP from 1950 to 1980: 2.2 percent per year

Growth in per capita real GDP from 1980 to 2007: 2.0 percent per year

Oh, and if we look at real median family income instead, we get:

Growth from 1950 to 1980: 2.3 percent per year

Growth from 1980 to 2007: 0.7 percent per year

Sorry: there’s no measure I can think of by which the U.S. economy has done better since 1980 than it did over an equivalent time span before 1980. It may be something you’ve heard, it may be something you’d like to believe, but it just didn’t happen.
