I see reasoning like this online all the time. A person donates $10 billion, and people say they it must have given them a warm fuzzy feeling, and that feeling is by definition worth $10 billion, because that's what they paid for it. As if the idea of selflessness or human goodness or anything existing outside the real of rational economic exchange is so challenging they find it more plausible that a warm feeling is worth $10 billion.

(Not that I think MrBeast is particularly an example of altruism - although it's probably an example of good)

Having behaviours that benefit your group rewarded and reinforced seems an obvious survival trait. It feels good, like reproduction. I wonder it's purely societal evolution or if there's a genetic component there.

Maybe it's hard to reconcile all this because calling something altruism is subjective, since we are not all knowing.

Like those act of kindness videos on YouTube with millions of views and earning the creators thousands of dollars.
