Former presidential candidate and CEO of Godfather’s Pizza Herman Cain took his message of economic prosperity to the University of Michigan last week where, perhaps not surprisingly, a number of students “booed” when Cain said we are living in the greatest country on Earth.

Speaking at a jobs forum on campus, Cain said: “Every time I run into someone who came here from another country, they always share with me their story, and reassert the fact that this is the greatest country in the world.”

“It’s not!” what sounded like at least two students shouted in protest.

As the crowd drowned out the hecklers with “boos” and a “U-S-A” chant, Cain launched into a fiery defense of his country:

If this is not the greatest country in the world, why is it that our economy is 25% of the world GDP?

If it’s not the greatest country in the world, why do we have more freedoms and liberties than anybody else…?

If it’s not the greatest country in the world, how is it that this nation was able to become the power that it is militarily and economically in the short 236-year history, relative to the history of the rest of the great nations in the world?

If it’s not the greatest country in the world, how is it possible to have a black man in the White House…?

If this is not the greatest country in the world, leave!
