My wife and i swing and swap with other couples. We've also had MFM and FMF 3-somes, but we would never fuck other people by ourselves. We do everything as a couple (in the same room) and with full consent from the other. It's cool that Richdad likes his wife to go out and fuck other guys but it's not cool that he has to cheat on her behind her back. That just sounds like they're not on the same wavelength and the cheating can cause problems down the road.
