Lyndon Johnson actually said...
And unless you become indignant, unless you people are concerned with the treatment of the poor in your town, unless you can get a boiling point, unless you can go out and look after your neighbors, unless you can make justice for others a deep, personal concern of our own, poverty will profit from those who exploit the poor and who have been exploiting them for all of these years.
