The "forgotten man" was originally coined by 19th century economist William Graham Sumner to refer to the "one percenters" who are forced to pay for the progressives' "charitable" impulses. These forgotten men are like a single sheep in group of animals consisting otherwise of a dozen wolves and jackals voting about what to have for dinner.
Since Roosevelt, the "forgotten man" has been used to refer to vast number of people at the bottom of the socioeconomic ladder who are often there because of progressive policy but are led to believe that they are the victims of the "one percent".
These people are hardly forgotten. They own the Presidency and the Senate.
