Number,
Forgive me for not directly answering your question. Also forgive me if I've misunderstood your post. But if I understand you correctly, what you are saying is that because (you believe) there are fewer B737-rated pilots than there used to be, you should now get a B737 rating?
Surely you are looking at this the wrong way around? The way I look at it, if there are fewer B737-rated pilots then that is a good reason not to pay for the type-rating myself. With fewer rated pilots around (if that really is the case), the chances are now better than ever that airlines will hire you without the rating and pay for your rating.
