Its an addiction like anything else. I quit caffeine a year ago because of heart issues, but i still cant shake the addiction to needing a decaf every morning. I imagine its similiar to relying on all your social connections through your phone. But worse.
I duno i can see pros and cons both ways. I work retail, and our jobs would definitely be easier without cash or coins. That being said, its kinda nice when you do something for someone, and they can easily just reach in the pocket and give you a 5 or a 20. Yes, I know you can do the same digitally, but its not as fast or reliable. Sometimes your phone isnt getting a good signal. Sometimes you don't have phone battery. Sometimes the other person doesnt have the same account to transfer digitally too. But with cash, all that is eliminated. Anyone who says theres no pros to a cash society is just lying.
