Thomson Reuters Municipal Market Data muniland expert Daniel Berger reminded me of a report that I had forgotten about that shows the correlations between the low credit ratings of Ohio’s cities and the cities’ very low levels of college graduates. Dan posits that Ohio, as part of America’s Rust Belt, didn’t require high levels of education for staff at its manufacturing plants and, accordingly, didn’t develop large college-educated workforces. As manufacturing moved out of the region, it left behind cities where the workforce was not attractive to high-tech industries and other sectors that required more educated workers. The cities declined and their credit ratings suffered. Such is the devastating effect of globalization.
