This is an interesting tell. If there are wealthy congregations out there who have given there surpluses to the borg then that could simply mean that there are no more extra money to go around for the borg at all. And that would explain there money situation right now. They have milked everyone dry. So now they have put up there two prize-posessions for sale in New York to try to milk those for the $1 Billion.
But what do they with it after that will be really telling. But how long will it take to sell it and how broke will they be?
