Does Rioting Create Jobs?

So Helen Reynolds asks, casting an eye on the disturbances going on in France these days.
Of course, riots create jobs.
They create jobs for:
police and security personnel
first responders
ER personnel
carpenters, bricklayers, ironworkers, and others who rebuild vandalized and torched buildings
auto workers who manufacture replacement vehicles for those destroyed in riots
They also increase job security for reporters and editors.
Maybe those sly rioters know what they're doing after all.
Maybe not.
