I don't know if the article references credit card interest rates, but I think it's worth also including in the discussion.

The graph on this page illustrates how consumer credit card interest rates have skyrocketed, and how obscenely high it is relative to the Prime rate. https://wallethub.com/edu/cc/historical-credit-card-interest...

I seem to recall that some years back the credit card interest rates were capped at a much lower rate than they are now.

Where this would lead us shouldn't be a surprise to anyone. And at a general level, many current systems in the US are on a clearly unsustainable trajectory. However this collapses, it's going to be really messy.
