Dale Belman, a professor in the School of Human Resources and Labor Relations at Michigan State University, writes in the Detroit News about the facts supporting paying prevailing wages:
Prevailing wage laws support improved efficiency through promoting training in the construction industry. The costs of operating apprenticeship systems are included in the wages paid under prevailing wage laws. Training is also encouraged by paying registered apprentices a marginally reduced wage until they finish training. In Utah, repeal of the state’s prevailing wage law caused graduation rates in apprenticeship programs to plunge to 15 percent from 95 percent. Given the shortage of trained construction workers, prevailing wage laws play an important role in the development of skills among construction workers.
