Exactly this, as schools in SF have begun to experience re-gentrification, back from empty nesters and influx of poor immigrants, the new gentrification has anecdotally resulted in improving schools at the elementary school level, and as they grow (and if their patents remain in the city) middle and high would likely improve too.<p>One of the stark differences between improving and flagging schools is parent involvement and support, in addition to a culture of education and learning.<p>It&#x27;s what I saw growing up, kids from blue collar families saw school as a reluctant obligation through which they had to pass.  Kids whose patents were professionals took a different view of education and saw it as a station on the path to a richer [both meanings] life.<p>So, it&#x27;s more than money or wages, it&#x27;s a way of thinking, how the parents think of school, how the kids think of school, attitude towards academic achievement (over sports, for example), etc.
