Earlier quoted context omitted.
Plunging saving rates? Saving rates jumped after the last crash. They are far higher in the US than countries like Canada, for example.
US savings rate actually dropped to a 12 yr low recently https://www.marketwatch.com/story/why-the-savings-rate-falli...
Considering the noise in that chart (savings rate drops from 11% to 5% in one month?!?), I would question whether it's really a trend and how accurate the data is.
One of my pet peeves with economic data - some leading indicator plummets after being high for years. Mass panic in news headlines, only for it to return to normal the next month.
