I always wondered about the relationship between Tommy Gambino and John Gotti. Was Tommy in some ways a non-threat to Gotti, despite his blood ties to Castellano, such that Gotti did not feel the need to eliminate him? Or was Tommy such a good earner, thanks to the Garment District, that Gotti could not afford to eliminate him? And yet, could not another mobster have gotten the same amount of money out of those rackets?

There is of course this remark by Gotti =

"I mean it sounds crazy, Georgie, but I was telling Frankie and Angelo, I'm gonna suggest to Tommy, we're gonna beef up his regime, Tommy Gambino, but we're not giving him no (expletive deleted) hotheads."

In any case, does anybody have any insight into the relationship between these two?
