Very good observation.  The nepotism I've witnessed from the inside of the OPS is out and out corrupt.  If the general public knew the public service has morphed into a multi-generational "nomenklatura" they'd tear the place down brick by brick.  If the public service wants outsized compensation then limit the term of "service" to 10 years (like most plum positions on the Public Appointments Secretariat) No more children of the longest time-servers getting in!  And certainly time to end the moonlighting that goes on with the firefighters, etc.
