"Economic suicide"? Nonsense. Solidarity between EU countries will be tested this winter, I’ll give you that. Hyperinflation? Yes, but that is also testimony of an overconsuming economy fueled by low interest rates. Eat less (remember that 30-40 years ago people spent proportionately way more of their income on food) , drive less (and use the bicycle), turn down the thermostat will do wonders for an overheated economy and the environment. Once demand goes down, prices and inflation will go down.
