I read an article a few days ago about how the Government would like to phase out cash so that everyone is compelled to pay by card or bank transfer, supposedly to make things easier and quicker and destroy the black market.
I actually think this is really ominous as once there is no more cash, there is no more anonymity and your spending habits and lifestyle can be tracked even if you are not doing anything illegal. Big Brother watching your every more.
It also means the banks can impose negative interest rates (where you have to pay the banks to hold your money) on savings accounts to get people to spend rather than see their savings reduced and of course also means that you don't really have control of your own money since the banks can collapse, bail in your money or appropriate it (as has happened in places like Argentina, not too long ago).
Cash is also really useful and personally I don't find it a faff to use cash. I think this is really scary.
