A high inflation regime promotes taking on debt as inflation makes it cheaper to pay off. That debt will get spent. If hyperinflation is threatened, buying inflation hedges is the “smart” move - real estate, gold, foreign assets. This similarly applies to simply not holding on to savings, as inflation devalues all money that you save at a faster rate than durable goods.
This is, literally, basic economics. And none of it is mentioned in the article.
Inflation is just rising costs. It includes price gauging and having to pay tariffs.
