Labor costs are typically seen as an expense, something to be trimmed and  managed,  rather than as an investment that can be optimised and leveraged.

All the fancy computer programs, training, and supervision in the world will not even begin to replace the value of an engaged employee who has some control over his environment, and recognition for making it more effective.
