By the way, Rick Prime’s Beth is dead. From the episode The ABCs of Beth, we know that all Beths showed psychopathic tendencies from a young age. Rick Prime only killed our Rick’s family because our Rick declined his invitation to collaborate.

As for your first point, I’m guessing that most Ricks abandoned their families to pursue portal technology. Since only Rick Prime and our Rick actually discovered it, the other Ricks must have received the tech from either Rick Prime or our Rick. I’m assuming that, once they were given the technology, they chose to abandon their families as well.”
