This song has a connection to Roger's past so allow me to give a bit of backstop first. Roger's father went away to war during WWII and never came back. His father was in the Royal Fusiliers and fought for the allies with Britain. He died at the Battle of Anzio in 1944. So this song is about his father dying in the war and how it tore apart his family and how he got the letter from the king about his death but he didn't care much and was too young to understand his father's death.

This is a very sarcastic song. The first part is mostly about how we are destroying the world for our own benefit and enjoyment. Then he says "A doctor in Manhatten saved a dying man for free." which, I presume, is sarcasm at it's finest. He's almost saying that even doctor's have little regard for human life over money that it's a miracle when a doctor saves someone who's dying for free, rather than helping them because they are another human being. The part after the first chorus deals with the theme of "Amused to Death", such as the thought that we have all these things that we think make us happy but in the end they really do not, we are just killing the Earth and in turn, ourselves. Right before the second chorus he says "and a farmer in Ohio has just repaid a loan." this is the same case as the doctor part. We care so much for money over our fellow man that it's a miracle when a person can pay off a loan that he needed to survive. The last part is just Roger Waters' hatred for Lloyd Webber showing. As most fans of Waters know, Roger has a supreme hatred for Andrew Lloyd Weber, so he believes when "the piano lid comes down and breaks his fucking fingers" that it's "a miracle".
