If a significant portion of the population has a market value lower than the cost for them to have a reasonable quality of life isn't that some kind of fundamental failure condition for society/humanity?
Is there a more rigorous explanation of why they count the probability space how they do? Watching that video I feel like the ordering of the kids and the striking of one of the "b2b2" entries seems wrong to me. If we care which kid was first... which doesn't seem to matter... then the first b2b2 and the second b2b2 seem like they're different and shouldn't "cancel."
Then again... it took me multiple explanations to understand the Monty Hall problem.
