Many of their earlier videos (before they started to do "What If" videos a la XKCD) focused on the confusing, absurd, and seemingly meaningless existence of humanity -- so much so, that they made a video on "Optimistic Nihilism".
They're quite reserved in the statements that they make, as well. They won't say life is meaningless, only that we haven't found something we truly agree upon as meaningful, and given that the universe is headed towards big crunch / heat death, what does it all matter?
Given those two points, I found it amusing that they'd go so far to say that simply giving someone $1000 a month COULD resolve misery, suffering, and existential angst. It seems to fly in the face of their ethos.
