Earlier quoted context omitted.
When was the last time you went to the bank teller and handed them $100 in cash? I haven't done that in well over 20 years now. Notes and coins represent less than 3% of the money supply in countries like the UK and US. It's not what money is any more.
So when you transfer $100 to your bank from another bank, the bank doesn't receive $100 credited to your bank's bank account?
If even the smart people on HN can't understand this it's little wonder the finance industry has such a stranglehold on society. The banks just run a ledger. That's all they are doing. But it's a ledger they control and they are allowed to create new money in it. In fact 97% of money is created by the banks when they issue loans.
It's a fundamentally different model to the antiquated "banks lend out your deposits" one.
