The analysis presents a false dichotomy between perfectly competitive markets and monopsonies in order to make an unfounded assumption that 100 percent of the labor cost decrease goes to employers in the form of pure profit. However, perfectly competitive markets are not required in order to generate the changes in labor demand and wages as discussed in this comment. As is normally the case for market-based economies, including the US economy, most markets are sufficiently competitive such that workers claim the majority of value gained from reduced employment costs (as the empirical research we cite shows).
