How are the ideals articulated in the Gettysburg Address speech still relevant for our country today?

Dude thats the 08-09 DAR essay question. Anyways what abe was trying to say was that we will all forget the words he spoke but he said to never ever forget what our ancestors did which was settle in this country to escape the monarchy in Britain which was kinda considered slavery. When America was finally claimed and was finally free, we started to have slaves and bring the anarchy to America. So our ancestors were mimicing what happen to them when they were in Britain in America. So tell me this is there still racism, and inequality in the United States? sorry if i didnt answer your question but tell me what you think
