The California based families existed in structure until the mid to late 1980s. After that they were dismantled by LE, and just kind of faded away because of attrition and lack of leadership and induction of new blood for manpower.

For the next several decades there existed a few made guys here and there who somewhat operated. The NYC families also had guys out there as well who continued to fuck around.

But let's face it, California is a different world. Yuppies, Puppies, and clear heads who don't understand, let alone adhere to mafia "doctrines." Hell, nowadays half the young Italian guys in NYC don't adhere to mafia doctrines. And they grow up right in the midst of it.

Plus there is a much, much smaller Italian-American population on the west coast. No recruitment pool.

The world has changed. The Jack Dragnas aren't around anymore
