Yes, but that's not limited to GS. As I understand it, the title inflation is an unintended consequence of regulations, tech, and cross-company contracts.
Workers are considered cogs in the machine, and only "sufficiently senior" employees are allowed to make any individual decisions at all. As a result, anyone who works with code and is required to actually solve any problems at all must be either "senior[tm]" or have one explicitly authorise every piece of work they actually do. For finance regulators and ivory tower governance people, agency is a terrible thing to allow for a drone.
Meaning? If you are in a role that requires to make choices and implementation decisions that affect production or path to production, you must be sufficiently senior. Ergo, a VP or above.
It's not just the regulations either - the contracts finance industry negotiates with each other also try to impose the same demands onto the other parties.[ß]
ß: I get to review these contracts at work. Some of the proposed clauses would require every possible change to be pre-approved by the most senior management.
