The only currency we have in the UK is sterling. It is government created. No one else can make it. It is the only legal tender we have. It can only be put into circulation by the Royal Mint, which is government-owned, and the Bank of England, which is likewise government-owned. We literally only have government made money in this country. And we have to use it: nothing else is accepted for payment of taxes but g0vernment made money. That is why we use it for our everyday transactions.
And there was me thinking that the banking system made a lot of our money by issuing loans.
Or is that only on Mondays?
