Later in this interview they get into public schools, and the implications of the lottery system. While this is well-intentioned this is really a terrible policy, I personally moved out of SF largely because of this issue (I have 3 kiddos so private school is not an option).
The example he gives is that despite living a stone's throw away from a high school his child was allocated to a school 1 hour bus ride away. This is really how it works for anyone living near one of the better schools. In addition to it effectively destroying the community aspect of schools where your kids go to school with the neighbors which facilitates neighboring families meeting each other and becoming friends, walking to school together, and so on.
The policy is well intentioned, but ultimately does more harm than good and everyone who is closely involved and knowledgable about the system is completely powerless. The voters just don't care what any experts or those affected say, they just vote on ideology. Quite frankly it feels a lot like the way in which Texas voters could not, evidently, care less about the plight of women with complications in pregnancy.
