The tank maker for the Soviet Red Army designed and built for a useful operational life of 6 weeks, and built 3 times as many units. The supplier for the Wehrmacht built tanks to last 9 months; but, couldn’t keep up with battle attrition. How did that work out?
Obviously, there are a lot of factors going on besides just output and quality. The end use of the product is a factor, as is the end customer. Regardless, the worker's wage should be no more and no less than his value to the company. His productivity and quality of output is a big part of that value. If the company's need is for a worker to produce 5 widgets per hour with less than 0.01% measured deviance from the the established standard, then the worker who produces 6 widgets per hour at that quality is worth more and should be paid more.
