Mammon of Iniquity

Created things are not sinful. They are good for God has made them. We are to use the created things God has given us to please Him, to merit His graces, to fulfill our duty and come to Heaven. But they become an object of sin when we misuse them. Consider our use of food, drink, cell phones, clothing, and time to excess or defect. We restore the balance with penance and fasting. Everything is good, but not everything is good for me.  So, what creature has become the mammon of iniquity for me?
