The way to read the debt-per-dollar ratio is this: It goes up until there is a big economic problem, it goes down while that problem is being solved, and it goes up again after the problem is solved.

It is important to note that when the downtrend ends and the uptrend begins, the economy for a while is very, very good. For example: the "golden age" of 1947 to 1974 or thereabouts, and the "macroeconomic miracle" that started in the mid-1990s. When the trend changes from downward to upward, we can expect the economy to be very good for some time.

Now... Look at the recent data at the right end of the graph. Debt-per-dollar has been coming down since 2008. It has come down pretty far. Not far enough, in my opinion. Still, the DPD lines are starting to flatten out, both of them. I think pretty soon they'll show up-trend. I think the economy is going to be very good, pretty soon.
I got the Graph #2 data from FRED. I looked at just the last part of it, since the fourth quarter of 2008, where the lines are going down. I took the red line, non-Federal debt relative to M1 money, and added a trend line for it. I used a polynomial trendline of order 2, and extended the trendline out 25 quarters (six years plus) past end-of-data. This is how it came out:

I've got the trendline equation so the numbers show a dozen decimal places. Looks funny, but I do that to get an accurate curve when I use the equation to re-create the curve.
After I got the equation, I made another graph like Graph #2 but with the black trendline added in. To create that trendline I used the equation shown on Graph #3. This time I extended it out to 2030. Have a look:

Remember: When the downtrend turns and an uptrend begins the economy for a while is very, very good. This is not going to be your typical anemic recovery. This is going to be the full tilt, rapid output growth, rapid productivity growth, high performance boom.
I can't promise you it'll last long, because the level of debt is already very high. But it'll be a good one while it lasts.

If only they would use the accelerated repayment of debt as their main tool for fighting inflation, we could have that permanent quasi-boom.
This is not investment advice
and as I always say, I don't make predictions.
I'm just looking at a graph.
