Where Has All the Money Gone - Part 2

Part 1 gave a hint at an answer (corporate profits.)  This post re-emphasizes the question.

The graph shows Real GDP/capita and Real Disposable Income/Cap since 1950 on a log scale.  (Data through 2009, from The Census Bureau. Table 678 at the link.)

I've left the 50's out of the argument, as a courtesy to Ike, since his relative performance suffers due to the post war baby boom - Ye Olde Denominator Thang.

If you've been paying any attention, you know there are break points in almost any econ measure, somewhere in the vicinity of 1980.  The trend lines here tell the same story - it's deja vu all over again.  BTW, I stopped both post '80 trend line data sets at 2007, to avoid the influence of The Great Recession, which would have have further deceased their slopes.

What I want to emphasize here is the difference between the two lines.  Though both have a knee, the Disposable Income break is much sharper.   Here is a graph of the difference between the two, linear scale.  And, BTW, this time I left the '08 and '09 data in the trend line determination. 

Well - since 1980(-ish) not only has GDP growth slowed, the amount captured in disposable income has decreased, quite dramatically.

That's a whole lot of wealth that is NOT ending up in peoples' hands, wouldn't you say?

Do you have any helpful thoughts?
