Teachers in California negotiate salaries with the individual school districts. I've never heard of any district anywhere in the state offering a top teacher salary of $160 grand. The supertintendent may make that or more, but then, he's a politician rather than an educator.
The retirement benefits are pretty good, but nowhere near that 3% per year and being able to retire at the tender age of 52. Here, if you quit before the age of 61 and a half (63 with less than 30 years) you get a pittance.
As for those health bennies, yes, they're great. A few districts used to pay for retirees health insurance, back when health care wasn't so expensive. That perk has gone out the window.
Teachers who are doing the job they have contracted to do, and that includes most of them, are worth a lot more than they are being paid. Teachers are expected to take on all comers, whether or not they are prepared for class or have any interest in learning or any back up at home, show progress with gang bangers and crack babies, keep order among children who have no other order in their lives, and put up with incompetent administration and a dozen layers of incompetent bureaucracy making assinine rules to live by. Teachers are grossly underpaid for what they have to do.
