That introduced me to the way the world really works. Before that I had a clue but there were lots of gaps in my knowledge that FtoF filled in. I have also watched Aaron Russo's interviews with G. Edward Griffin that go into more depth and personal insights. He was a brave man. RIP.
"Jesus answered them: 'Truly, truly, I say to you, everyone who commits sin is a slave to sin. The slave does not remain in the house forever; the son remains forever. So if the Son sets you free, you will be free indeed.'" (John 8:34-36)
