It really is just such a terrible idea/concept it's kinda staggering it would get made.
Entire cities would burn, roadways would be destroyed, homes destroyed, work couldnt just resume the next day, major bosses would be dead, places of work burnt down. Why wouldn't the mcdonalds corp. form armies and go and burn down burger kings and competitive food joints?
It would just destroy the country and then people wouldnt stop, it would be a continued cycle of seeking revenge via murder until marshal law would be needed and than everyone would band togeather against the government that caused it all and is further trying to opress them. That's the only way it could believably end but if I'm not mistaken in the movie this is something that's been going on for years so yeah...
