Once upon a time folks looked at breeding money the way Americans look at breeding siblings.  Something that shouldn't be done.  A perversion.  An act that takes a thing that's supposed to be barren and makes for bad offspring.

The janitor's about to review something I told you back in Chapter 9 -

Breeding money's how we got to plastic sacks

Although truth be told the janitor should have used the term 'inbreeding'.  Because once humankind had wrangled a couple dollar bills they took to mating them like dogs.  But don't forget.  The first two dollars they started with were family. 

It's 1987. 

We're twenty generations deep in a bog of inbred genes.

If you've ever seen a white plastic grocery sack blowing across your tidy suburban street and found the sight ugly, grotesque, malformed, revolting or offensive to your senses . . .

if you've ever stumbled upon a white plastic sack stuck in the muck of a gutter and thought of all the disagreeable aspects of the frustrated, frightened century in which you live, this jangled century of trash and heavy industry and total waste . . .

Consider its pedigree.  Consider the family tree.
