Detroit Public Schools 50 plus years ago had done a much better job in prepping it's students for the job market and the global market than they had done presently. There were many trades that students had learned including math, science, business, and law. Students were also learning to fly. Computer classes were installed in the 70s. Why hadn't Detroit tapped into that talent that were in DPS and use them to attract other businesses from across the country or start up local firms that could hire these talents?
