75 Solutions to Fermi's Paradox but Still Missing Mine

I revisit Fermi's Paradox and my explanation for it, in light of the second edition of Stephen Webb's "If the Universe Is Teeming with Aliens...Where Is Everybody? Seventy-Five Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life". I find several places, where in my opinion Webb shows a lack of imagination. Then as a Christmas gift to myself I explain how too great of a focus on social justice may be keeping us from getting off of our own planet.
