The Incredible Bread Machine Film (lessons in real world economics)

At time 20:00 there is a narrative on urban renewal which states the number of housing units destroyed are greater than the number replaced. This net loss of housing would of course create a housing shortage which would allow the justification of additional government intervention in housing. Government having created the problem allows government to step in and "solve" the problem.

This is exactly what will be happening with Marin City.  Good buildings will be destroyed and a community displaced.  Future residents will be "mixed income" i.e. gentrified and the needy families will be priced out of the community.
