I am of the impression JB runs it like the mafia. No money but things that may or may not have 'fallen off the truck'/been given by sponsors and a house for your family. Just follow along the script, don't embarrass us and you will be allowed to live just above the poverty line with minimal effort.
I am glad Derick and Jill have something JB cannot take away. An education for Derick and a house they may have gotten through other means. And freedom. And a story that would make a ton of moola should they decide to spill.
