Piggy's glasses symbolize power and intelligence since while he is not physically fit and healthy, his intelligence makes up for it, making him one of the smartest characters in the story. It also shows power since Piggy's intelligence helped him help the other characters survive.
I believe that MLK's dream has not completely come true in present day America. He states that "my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character". However, in recent news there was a rise of police brutality that is completely on the basis of discrimination. In order for his dream to come true, there should be no possibility of anyone, or his children, being treated differently due to skin color. I am not entirely sure if this discrimination applies to all social classes, but I know that we still have work to do in obtaining this dream.
The kings did turn against the harlot and cause her destruction.
