To build on that - the point of these proposals isn't to cover the teacher who has been in the district for 30 years though. It's to cover the young teacher they have to hire when the older one retires. They are likely having issues hiring anyone that can actually afford to live in Palo Alto. Because of housing costs, it's next to impossible for anyone to move there and establish roots in the area (read: buy a house). This means that you're going to see more volatility in the labor market for traditionally middle class government jobs (teachers, police, etc). That will be important to try and balance in the future.
