What is an american?

An american is obviously someone who lives in the U.S. but more importantly americans are what make the country run the whole structure of this country wouldnt function without every person doing their part i mean someone has to work at the grocery store so that we can buy groceries right? American are the building blocks for our country, they do what needs to be done to keep everything together but American are also free something that many countries don't have in china once you reach a certain age you are told what you are going to do for the rest of your life (Communism) where here we do what we want and we do it how we want to...(to a certain legal extent). So every American has the option to do what they want to help run our country some people become doctors to treat the sick, some become teachers that educate our youth, some become McDonald's workers that keep us in the lead for most obese country but all of them have the choice and all of them play their role in keeping America running. another large part of being an American is being diversified. I mean way back when we were called the "melting pot" and that has kinda stuck with us. we have all walks of lives people from all over the world come here to live. Which has taught us racial and religious tolerance, and has also added a lot of things to our lives that we wouldn't enjoyed had we not been so diverse.
