native american contribution: the patriots from britain learn how to hunt, fish, and introduce diversity within cultures.

african americans: indirectly introduced the idea of diversity to americans. africans coming to america because of slavery taught white americans that people come from different backgrounds and colors. it also built america's economic stability for a great period of time. 

women: make america what it is today. there are some societies that are in the world currently that do not give women the same right we give women here in the united states. because women have rights here in the united states, other countries' citizens strive to come to america, especially women, since they have equal rights in the united states. this is important because america is seen and desired by many in the world. 

children: children are our future. we learn from our elders and carry out things the same or differently learning from america's history. we continue tradition and change tradition if it is needed. 

during the debate over his landmark energy policy proposal, president jimmy carter failed to consult one of the most powerful senators, louisiana’s russell long, who would have a big say over whether the legislation moved through the upper chamber. this was classic carter. with a strong distaste for congressional politics, the president simply refused to do what most other presidents would consider routine, such as courting key senators. long became so irate with the president that when he was finally invited to a white house dinner, he stood up to ask a question and, before doing so, proceeded to sarcastically introduce himself: “i’m russell long, chairman of the senate finance committee.”

this interaction is a revealing moment in stuart e. eizenstat’s fascinating new history of carter’s presidency. the former peanut farmer from georgia was a president who, according to conventional wisdom, didn’t care much for party politics; nonetheless, in eizenstat’s view, carter’s legacy on domestic and foreign policy has been vastly underappreciated. the author paints carter as a “bold and determined” leader who bravely attacked the challenges of his time. eizenstat goes so far as to argue that carter might very well be the most successful one-term president in american history.
