GRE revised general testing & TOFEL

Winston Churchill said : "I took the taxi one day and went to the BBC office for an interview ... and when I arrived I asked the driver to wait for me for forty minutes until I got back! But the driver apologized and said 'I can't because I have to go home to listen to Winston Churchill's speech' ... Churchill says he was amazed and delighted with this man's desire to listen to his conversation! So Churchill took ten pounds and gave to the taxi driver without telling the driver who he was. When he collected the money he said: "I'll wait hours until you come back, sir! And let Churchill go to hell! *Principles have been modified against money* . *Nations* were *sold for money, Honor* was *sold for money.* *Brothers* were *sold for money* . *Families* were *split for the money* . *Friends* have been *separated for the money* . *People* were *killed for the money*!
Who gave so much power to money and made people their slaves?
