Peter Phillips, an economist at the University of Utah, is an authority on construction labor issues who has written numerous studies comparing costs in states with and without prevailing wage laws. His latest study compared cost data for 391 school construction projects from 1991 through 2000 in Ohio, Michigan, and Kentucky. Prevailing wages are developed from surveys that request wage and fringe benefit information from all contractors regardless of labor affiliation. The state compiles the data and sets prevailing wages and benefits. The prevailing wage in any state is the average of all wages and fringe benefits paid to employees in a specific field or craft.
Local markets determine wages.
Both are grossly over budget and behind schedule. You get what you pay for. Instead of blaming government, look at the projects that are over budget and behind schedule and the reasons for that.
