Decline in on-the-job training (buried at the bottom) is the most import stat here; more important even than declining tenure. Training speaks to what employers are 'buying' when they hire someone and engages with other trending topics in econ research: the changing skills-mix of jobs (i.e. the weakness in the middle), the employability of college grads as the metric for the worth of a degree. A positive take on this is that free resources make it easier for people to self-train so jobs don't have to train you. The negative take is that 'labor alone' is of declining value and we're increasingly employing people for their 'information content', not their rote performance.
