Kings say the dream of America is “as yet unfulfilled.” Do his words still hold true today?

yes, because the world has not seen it's end we can only assume this is just the beginning. Not only are we still developing technology but we are creating a new path for ourselves and others. His speech was about how differences don't matter or they shouldn't but as it quotes "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and pursuit of happiness." This is the dream. The first things we notice in this dream is an amazing universalism. It does not say some men, but it says all men. It does not say all white men, but it says all men, which includes black men. It does not say all Gentiles, but it says all men, which includes Jews.  It does not say all Protestants, but it says all men, which includes Catholics.
