A fascinating and foolproof strategy for political speechifying is to make mostly sweeping statements that are vague enough that listeners are forced to subconsciously fill in the blanks for themselves. Take this sweeping-but-vague statement: "We need to create good-paying jobs to bring this country back to its former greatness." To be truly meaningful for listeners, this statement needs more specific definitions of terms, such as an actual wage range in place of "good-paying." However, instead of providing specific details, politicians purposely allow each listener to mentally substitute his/her own version of "good-paying" with satisfactory wage ranges of their own.
What is meant by "former greatness" in the above statement? It doesn't matter because listeners will specify the meaning internally. Each of us will automatically plug in our own definitions, while simultaneously giving the politicians the credit for delivering speeches we can relate to, yet avoiding any accountability for their details.
