“Every state that has a sovereign currency, and isn't mired in foreign currency debt, issues money into its economy in the way described by MMT. How it handles its economy after doing that is a matter of ideological and political choice”
Yes, they do but all have to trade globally, most commodities are traded in US dollars. If confidence is lost the local currency get devalued, many states have worthless currencies, countries like Argentina where Inflation is 50%, 100%, 200% and all commercial trade is done in dollars.
Weve all been on holiday to those places where tourists pay for most services in dollars because the local currency is so unstable, even India which is far from the worst.
So let’s print unlimited money and watch the sterling plummet, thankfully that’s not going to happen because this government and the previous governments realized (except Truss) how stupid that would be. It’s all about confidence, which is why QE is counted as borrowing so the money supply is transparent and everyone know what’s happening.
