Over 50 years ago two political scientists noticed something profound about the policy agendas in America, the things that are missing (along with those issues are the people who have them). Since then, that observation had become pedestrian. We talk about people who are forgotten, who don't make the news, and who don't get any attention from politicians. Often, they are marginalized populations with little power.
Some pundits argued that the people who have been forgotten are the white, lower-to-middle income people who were left behind in the economic expansion. Globalization is not the first instance of economic changes leaving people behind. They are often invisible to the wider society, languishing in their misery in private, without opportunities or choices. It's worth know about those struggles, which have re-emerged in our last election. Resistance is sometimes subtle, sometimes not.
