That is an interesting chart. Haven't seen that before.
Depending how accurate it is, much can be inferred from the data. For example, looking at the "quits," one can infer that the macro effect of a relatively constant retirement rate would yield important information for the SSA (i.e. cash flow, cost of living adj, etc.).
Another example is how the "job openings," roughly correlates with GDP. Like I said, interesting graph.
