alt Hacker NewsThe correlation is backwards. America’s mid-20th-century dominance was not the result of having only about 10 percent college graduates. It came from unique post–World War II advantages: intact industrial capacity, massive federal investment like the GI Bill, NSF, DARPA, and the interstate highway system, and the fact that global competitors were rebuilding from destruction. The GI Bill greatly expanded access to higher education and economists widely credit it with boosting productivity, innovation, and the growth of the middle class. Rising college attainment in the 1990s and 2000s coincides with globalization, offshoring, and wage stagnation, which makes this a correlation problem rather than evidence that more education causes national decline.
It was 10% of the US population who went to college before the GI bill, which then doubled to 20% over a decade following the war. Now >50% have post secondary. 70% attempt post-secondary after high school
Before WW2 only about 40% of people completed high school, now it’s at 90%
