In a way it's the way you look at things....

The Feds say the Genovese are the Ivy League and top OC group and he is the boss.

So Barney needs to be near the top of course. I have also read he has many legitimate streams of income that make him legitimately wealthy so he has to be near the top. And the Chin who many regard as one of the best bosses after the rico act picked him so i am sure he is a powerful guy..

But it is a secret organization so we really don't know.

And hearing some of the numbers thrown around in Gomorroah and about the cartels it is possible that a guy big in the drug business would have tons of $ and with that power...

But drugs are a tricky thing and things can come crashing down very quickly as we have seen in Canada...

I am sure the Gen Gam and Luchs all have some pretty powerful and heavy guys but in my opinion it would be tough to say who is the "most powerful" and besides that how do you define power???

Is being able to shutdown a $20M construction site more powerful then being able to get shipment of drugs from Italy?

I don't know??
