On one of my rewatches of The Legend of Korra, I noticed something about metal bending. All of the metal benders we're shown are either in the police force or have status. Think about it, Toph's kids with the Beifong name and probably some money (look at how fancy the metal clan is), Kuvira, and the police force. And when Kuvira fights the earth kingdom bandits, she takes them down with ease because they can't metal bend.
Could there be a 'class' divide between metal benders and earth benders? Bolin probably never received metal bending instruction when he was living on the streets with Mako. It's possible the first time he was taught (although unsuccessfully) was when he went to the metal clan. So the only way to learn how to metal bend is to have the money to learn or join the police force.
