So your saying that America was built by the labor of the people who came, freely or in bindage to the shores of North America and their labor; blood, sweat, tears and their very life essence provided the power or energy to transform a rugged undeveloped continent into the worlds most powerful nation. Wehere people came from every corner of the globe and adopted a common language, common culture, common political beliefs in truth, justice and the rule of law. And they formed America.
Powerful Stuff indeed, worthy of a movie.
