US v Aussie wages v cost of living

My techs average 45,000yr, I pay their health insurance and 1/2 of their families. They get 10 days paid vaction ( we are closed 4th of july week and week between xmas and new year) 8 other paid days off and they work 4 1/2 days a week. I pay for training and they are expect to go between 20-25 hrs a year on their time.
