Unless you tell the fed to run inflation at 20% for a few decades and tie everything else (wages, pensions, welfare, etc) to that rate. It is called fiscal repression and it has it's drawbacks, but it would serve to end inequality by making everyone billionaires. (The price of a coffee might end up at £1m though..)
This is often the reality. Massive wealth inequality won't be fixed by making everyone billionaires, it'll be fixed by getting rid of billionaires
