It's true that carrying as I have understood the letter of the rule in the past (hand below the 'equator' of the ball) is almost never called.
I would (and have) go further and say that the "legalized" carry has done far, far more to change the men's game - particularly at the NBA level - than almost any other single factor in the game. This is because so many things follow, like a domino effect, once the carry is no longer called. Check out and old Knicks NBA championship game on ESPN Classic sometime from the early 70s, or older games from prior decades. Very little carrying. Much more reliance on ball movement and much less reliance (and ability) to simply blow a defender 1-on-1 if both are stationary to start with.
Even Michael Jordan carried the ball regularly, which was insane as his hands were almost as big as Dr. J's hands. At least most female players have the excuse of much smaller hands, even though the smaller ball helps somewhat.
