What does the phrase "we have come to our nation's capital to cash the cheque" mean in this context ?
Five years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation. This momentous decree came as a great beacon of light or hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of their captivity.But one hundred years, the Negro still is not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and chains of discrimination. One hundred years later, the Negro lives one the lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languishing in the comers of American society and finds himself in exile in his own land. So we have come here today to dramatize a shameful condition.
In a sense we have come to our nation’s capital to cash a cheque. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This was a promise that all men, yes, black men as well as white men, would be granted the inalienable rights to life, liberty and the pursuit of happiness.
