They create their own rats through greed and stupidity quite a bit. Even the Westside was culpable for shelving Georgie Barone when he wasn't ready to go.

Take it from me, if not for that boneheaded move, that old man NEVER would have rolled. Trust me on that. And keep in mind, he gave the Westside twice as many years as Scars gave the Gambinos. Maybe three times as many.
