It appears the net you've cast for research, as far as MC's, fell a bit short...or you have very limited knowledge on what exists other than what is popular in mainstream media. There are many...they are seasoned <40 may have been "old" a couple of decades back..now's a bit different>...and they continue to be the "gifted storyellers" you mentioned...
Most, if not all of them <"old people MC's"> pretty much have opted to keep their dignity, their craft, and most importantly their souls away from the <lower level consciousness> subject matter that are popular topics for the masses.

b. Regardless of what anyone says or how they feel about Hip-Hop, it's not dead.
c. Hip-Hop is for EVERYONE...but sadly not EVERYONE can be the best most seen, or heard MC, Turntablist, Graffiti Artist, Breaker/Popper, or Beatbox.
You battle for those titles-

The craft is the craft-
