You brought up an excellent point, the 5 Families will be around for more decades to come because they're still recruiting, per recent revelations, even the Colombos. I actually think the Colombo Family is a good indicator for the health of the other Families, if the weak Colombos are still recruiting and trucking along, then you KNOW the other 4 Families are doing okay, and in the case of the Gambinos and Genoveses, beyond just okay.
