I think companies have pretty clear life cycles. First they start, they grow, then the plateau, and then fall. Sometimes you may get a few bumps in the road, but generally this is the long-term cycle.
Financialization makes the most sense to engage when when you are plateaued and possibly falling. You can still extract value.
I think that the fall of Sears was a great example of the financialization and extraction of value of a dying company.
Financialization is trading off future potential growth or even long-term staying power for $$$.
