King used a financial metaphor to refer to the lack of compliance with the civil rights that the Declaration of Independence and the Reconstruction Amendments to the US Constitution (14th and 15th) included for all US citizens, without discrimination in terms of race.
King aimed to express that the US still owed, to its black citizens, the defaulted "promissory note" that Martin Luther King Jr. had mentioned and demanded in his remarkable "I have a Dream" speech, delivered in 1963. Instead of guaranteeing the promised rights of life, of freedom, and of the pursuit of happiness, black people had received a black check, one with no funds on it and were still waiting for the payment of such debt.
A) <span>On this day in 1956, the U.S. Congress approves the Federal Highway Act, which allocates more than $30 billion for the construction of some 41,000 miles of interstate highways; it will be the largest public construction project in U.S. history to that date.</span>
I that it comes from the fact that America was supposed to
be the country where all men are free and equal but when it comes to Blacks,
that does not apply. Despite fighting a
war that restored the Union and freed the slaves, Blacks still did not enjoy
the same rights as white men hence the contradiction.
I'm sorry to say but your question has been falsely posted in the History section and should be placed in the proper science section. Have a good day :)
