yep ..you're the complete other side of the coin..no pun intended...
There is definitely a need for Credit and Debit cards... but ease of use, laziness, perceived safety.. has turned the western world into puppets of the master... and before long the majority will cause us to become the Slaves of Big Brother..
As you are already aware Deb, once you have no independent control over your finances and it's taken by the Govt of the day... then you have lost control of most other things in your own life..
It's already happening...fast, with the disappearance of Bricks and mortar banks meaning people have less access to cash, forcing them to use card to shop online or instore...
Information, independent thought, and freedom will eventually be restricted..(information is already severely restricted in many places in the west and especially so in the East ) and sadly the majority don't realise it..... . A figurehead or concept will eventually worshipped by the citizens of the society. Citizens are perceived to be under constant surveillance. ( and there is nowhere more watched than China and the UK ) and eventually Citizens will have a fear of the outside world.
