I'm just like you that not an economist but I think it was only inflation is the ones that can destabilize a country or the ones that is a threat to it and not deflation because it was the opposite of it (inflation) which means it can help us to bring back the low value of the goods again, or can bring us the true power of our local currencies again.
Deflation is far worse than you think, just because it grants you cheaper goods it also comes with an avalanche of other effects. For example, cheaper goods mean lower wages paid, right, because there is not point in selling a pizza for half of the price and still paying the delivery by the same, lower wages mean also less consumption and as prices go down people are not keen on buying stuff like houses or land or cars, meaning unemployment in the construction sector in the industry, and then a death spiral like it has happened last century.
agreed with this, debt is also one way that become the culprit of economic threat, it also correlate with inflation,
Yeah because Japan in a deflation period having a higher GDP/debt ratio than Argentina experiencing 200% inflation is obviously an example of that.
