This model does depend on the idea that most homeowners think that public transit will bring poor people and/or crime and thus would lower property values. There are lots of examples of homeowners blocking transit and then complaining about traffic. There's a lot of evidence for this in the '70s; this was super tied up with wanting an ethnically and economically homogeneous neighborhood. it explains a lot about where VTA goes (and why we have VTA in the south bay and not BART) The evidence for this is not as strong now.
