Arguments about prevailing wages have not changed much since the 1980s, the last time the U.S. government changed methods under the 1931 Davis-Bacon Act to determine a prevailing wage on most construction projects with federal funding. The Biden administration has opted to return to the three-step method used before 1983 to avoid overreliance on weighted averages.
This obviously is a way to capture more union collective bargaining agreements in the wage determination and boost required payments by any employer on covered projects.
