For the better part of a decade now, major socio-political disruptions never seem to rattle markets. Think back to Occupy Wall Street, the events in Hong Kong over the last year, or the protests in the US over the last week. The question is why? The main reason is that historically speaking—think the entire 1960s and up through the 1992 riots—markets and the economy were never particularly affected by social unrest in the months following big social disruptions/protest.
FINSUM: Essentially the argument here is that there is no precedent for needing to worry about social unrest. That approach only makes sense until protests do cause a big problem.
