It is worse than slavery because companies found they can create an environment for motivated wage slaves constantly competing with each other, aka 'culture'. And fire those who lost motivations in order to strengthen the 'culture'. As a comparison, traditional slavery is extremely inefficient because traditional slaves are far less motivated, the master has to spend his time or hiring people to constantly threatening and beating slaves work.
