I've worked 30 years for the State of California and I agree that there is lots of corruption. I saw rampant nepotism, lots of hankypanky in giving out contracts, just plain tons of waste and duplication of services, you name it. As a lower level employee, I would have disappeared if I ratted them out, though I did make many discreet calls.
Now I'm fleeing for my life.
Not reporting corruption is your choice. That is not the choice I would have made for myself.
