The first phrase in the first sentence makes it clear. 'The scale of advantages' doesn't mean anything, except in the an unlikely context where you're talking about the relative size of various advantages - whatever that might mean.
The use of 'scale' in the last line but one is a lazy usage encouraged by MBA courses. When I was a lad, scale didn't mean bigness I'm afraid a lot of people use it now as if it did.
