Hmmmm. Money indeed holds great roles in our lives, cause without money there's nothing. Also, money speaks a lot that's why you will see people running after money or doing nasty things to earn the money. As how people say money speaks, if you have the money then there's nothing you can't do with the money. Also, for some money represents freedom to seek the pleasure of travelling around the world, and buying things that are not that important just because you have the money.
Money also influences power, for example, if someone witnesses a murder scene, because they don't want their secret to be exposed they will bribe the people to keep his or her money shut. Money changes someone's life and likewise, destroys someone's life.
