My question is,what happens to Sonny and Fredo?
How do they make a living?

I can only guess that Vito,Mike.and Tom could manage to set up some legitimate businesses for them,so that they could have a legal income.
What about the rest of the Family associates?
We didn't really see them in the movies,but the Corleones must have had quite a few members.
It's quite possible that they could be absorbed into one of the other Families.,and continue in the rackets.

Any thoughts?
Sure thing Lou if “Vito decides to end the Corleone's involvement in any criminal businesses” Difficult not Impossible “to get Mike – who has never been arrested or indicted for any crime whatsoever No proof linking him to any criminal conspiracy - elected to a major political position”

And if the Corleones ever need muscle they can always draw the water from Clemenza-Tessio-Family associates' well, discreetly!
Obviously their Family is not still called Corleone!

The Corleones already had their “legitimate business”! Their Genco Olive Oil Company as their Front
All Vito has to do is launder their blood money through Genco

Tom “as in-house Lawyer”

Carlo could be provided with something important ie: more than a living, in Genco
After all Carlo was gonna be Michael's right-hand man! in Nevada

As you stated “Sonny would never have the intellect or temperament to rise above the basic leg-breaker level” loose cannon indeed
Lemme think about it -- Oh, well, we'll see -- we'll see! Come on -- We can come up with something in it! for Sonny
