POTENTIAL
We're a great country that's done so much, but we DO have flaws, and we're not close to the greatest nation on earth anymore. With our GDP, population, cultural influence, and science we could eradicate so many more diseases, dominate the space race for the next 100 years, humiliate other nations in how good our infrastructure is (ours currently gets a D+), and could be the most united nation on earth.
And to those who say we can't because we can't be united because we have different cultures and races: America is about destroying people's expectations and doing the impossible.
