Companies pay enough to get the quality and quantity of employees that they need. This is an assertion not presently supported by evidence. With any other resource they need, companies typically respect the law of supply and demand: when there's low supply or high demand (or both), they pay more to get the resource. But when -- and seemingly only when -- that resource is labor, paying a higher price is practically unthinkable. That's why we've seen decades now in the US with little or no (inflation-adjusted) wage growth, despite higher average productivity and periods of low unemployment (either of which ought, in a rational market, to produce higher wages).
