Pretty much every company I’ve been in or know of values a vertical trajectory instead of a horizontal one for its employees i.e becoming a manager nearly always means a faster salary progression than becoming an expert in one or multiple fields.
Why is expertise valued less?
Sure but “multiplier” by 10x or 1.1x?
IMO managers/bosses are there to take care of the anoying little things so the workers can focus on work. Workers can do all that and even organize amongst themselves (most of workers can). And there are thousands other variables. Question is of pay, so the question is of worth. IMO a manager is not always more worth then a worker, and I wonder how often one is.
Disclaimer: I worked construction and a bit of sales, not an office job.
Correction: 1.1x, not 0.1x.
