Fallacies in Famous Speeches

Speech: JFK's "Inauguration Speech"

1) "If a free society cannot help the many who are poor, it cannot save the few who are rich."
2) The fallacy is the confusion of correlation and causation. A society's inability to help the poor does not cause it to fail at saving the rich.
3) Although many famous speeches rely heavily on rhetoric or fallacies and do little to support arguments with true evidence,  the audiences they are geared toward do not always require great reasoning. The brain is wired to respond to statements that sound and/or look good, so even educated individuals are effected by the tricks of rhetoric.
