The highjackings gangsterreport mentioned were a case of the family forcing a partnership (basically taking a cut) from some guys running a stolen goods ring. It was more of a street tax thing than a scam like betting into a book with no intention of paying any losses.

The 2004 New Jersey OC report stated that the Philadelphia family lacked the wherewithal to really expand into legitimate interests. And cases since then have largely born that out. Ligambi, for example, was said to have investments in real estate, a towing company, as well as his 50k a year no show job with the garbage company. I imagine some other members have legit interests too. But, in terms of the organization as a whole, it seems to be a street operation at this point. The bulk of it centered around gambling, ie bookmaking and video poker machines.
