A lot of comments here are using word like "promotion", starting at the "bottom", powers reserved for "higher ups", etc. following the standard framing of hierarchy as a vertical pyramid, which I think possibly encourages the view of promotion as status. My favourite reframing of team hierarchy is to change the language to make it horizontal or fully inverted. In the horizontal case, promotion might be 'stepping back a rank to help co-ordinate'. In the inverted case, promotion might be 'stepping down into a supporting role' (although that particular language bumps into confusing euphamisms left over by the pyramid framing). I'm sure some better language can be found but you get the idea.
