The well-off and the secure have too often become indifferent and oblivious to the poverty and deprivation in their midst. The poor... have been shut out of our minds and driven from the mainstream of our societies, because we have allowed them to become invisible... Ultimately, a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for 'the least of these.

— Martin Luther King Jr., Our Daily Journey with God
