I agree that Scarfo would have been better not as boss - he is LCN all the way so if they had a more level headed boss he would have obeyed the rules and not brought the family down. Scarfo shook down the dealers in Philly and South Jersey - street tax is when they started making a ton of cash. It does look like he allowed his fam to enjoy their money and share the benefits - using the boat in Florida, jersey shore etc ...
All that being said Scarfo was way to public -- uncle joe had a good run although much less earning but he wasn't greedy and didnt have too many enemies I don't think.
