What? Where have you got that from? The companies are already charging as much as they can to maximise their profits.Companies don't care about profit?
It's you that's suggesting they could charge more and earn more if they wanted, but they don't.
They will have contracts that protect them. And as I explained, the likes of Starbucks wouldn't just put up the prices anyway, because it wouldn't work.Oh and great, all the existing franchise owners get screwed.
