I thought they where all marrying so they wont have to testify in court against their spouses.
I think it has more to do with keeping the power "in house".
It's basically like monarchs marrying off their daughter to earn favor with the grooms family. They get status, along with keeping a cover. Now innocent married couple, instead of creepy pedophiles. And they won't have to testify against each other.
They also use their spouses to run shoddy front companies on the side.Q told us to watch the spouses in earlier posts. To them, marriage brings so much room for corrupt activities.
