"So why all the talk of a shortage?"

what is S of this? or V?

Hi,
This isn't a grammatical sentence (though it's the type of thing that's commonly said).

The full meaning is:
Why are so many people taking about...
Why are you talking so much about...
or
Why is there so much talk about...

So the subject could be "you" or "people" or even "the talk" depending on how you wrote it out in its full form.

thank you!
it' very clear!
