I´ll agree it is a fantasy collage.  I don´t think the point was that more minorities will ride transit, old people will hold hands, or hipsters flashing peace signs.  Regardless, it is kind of... redundant.  Everyone wants to grow old and be happy, everyone wants public transit to be utilized better, everyone wants good food to eat and prefers that it is from a local farm, everyone wants happy children and a cleaner planet, everyone wants preserved parks.  Thanks, Sightline, for the obvious.
