One big difference is that public companies restructure when things aren’t looking rosy. Government organizations don’t often reorganize and structurally they don’t have much flexibility.

The government restructures endlessly what are you talking about.

DHS was founded in 2002, TSA was founded in 2001. CFPB in 2010, Space Force in 2019.

Even agencies that have been around “forever” aren’t that old. The EPA was founded in 1970, and OSHA was founded in 1971.
