Researching the older Southern / Midwest US Mafia Bosses pre Internet days, it seemed like they had a easier go of it being the heads of their families then the East Coast guys

Carlos Marcello had a very long reign as the New Orleans
Santos Trafficante like wise in Tampa,
Nick Civella....KC...John Scalish.Cleveland...Joe Zerlli..Detroit
On and on.....
Those guys put in 30 plus years as mafia bosses.

But the NYC bosses had a higher turnover rate .
It is because the bosses west of NY had smaller families
Thus less issues to deal with or does it go deeper than
That ?
