Good point, as is your derivative idea. I'm just running on that scratchy feeling in my brain that this all does not add up- the actions taken are at odds with the events supposed to have incited them. It feels incomplete- as if a big piece or two of the puzzle has been kicked under the table. Capitalism searches out the darkest corners of human potential, and mainlines them.
