Ok, I misread your original reply and did not see that you had reduced your selection set to look at the Chicago area BLS numbers rather than national. To your point on junior devs progressing through the ranks, registered nurse is also entry-level and the expectation is that RNs will progress to expert/mentor/manager nurse, a specialty, etc.
However, I have pretty big issues with BLS data in general, so it's pretty clear we're not going to come to an agreement here based on that data set. If you're going to treat BLS data as gospel and other sources as garbage then we can save time and stop here.
