It would be helpful to have more on urbanization and rural exodus and the effects of these on American culture. Ideally there might be work that takes this American framework and puts it in conversation with what we know about social mobility as it relates to Hawaiʻiʻs plantation history and the deeper history of Hawaiian subsistence practices.
It would also be nice if research existed about more of the various food activist groups in Hawaiʻi and how they articulate the problem and their vision, goals, ethos, etc.
As mentioned in the Wilkins annotation, it would be nice to balance out the research into consumer-citizen identities to find out to what degree they are helpful in achieving food self-sufficiency, and also apply this to the specifics of Hawaiʻiʻs situation. In what ways is the consumer-citizen identity useful compared to producer identities found in Hawaiian food activist rhetoric, for example?
There is probably more work out there about immigrant assimilation to American culture and how food is entwined with that.
There are probably more eloquent sources out there that articulate from a Native Hawaiian perspective the importance of rural lifestyles, agriculture, and particular foods to Hawaiian identity.
