Well, actually, grievance plays a rather important and quantifiable role in world markets.
It's insurance (health, liability, disaster) which is a form of prepay grievance.
It's selling short and put-otions in the market -- which is grievance in its most abstract and profitable form.
It's prenuptial agreements. It's certainly lawsuits, it's even jihad along with the martyrs reward.
Our entire crime-and-punishment legal system is based on grievance.
Oh, I don't know -- I'm rambling now -- but it strikes me that it is the yin that make the yang possible.
Nice essay, as usual.
