No debt problem for the consumer or for corporations. What I see is a deceleration of growth to trend, coming from a 2018 growth level that was above trend. At-trend growth is "good" and "normal" and "sustainable".
The non-problematic December 2018 blip in the first FRED chart is now a thing of the past with the stock market recovery since Q4 2018.
