Edit: This is actually more deep (as mathematics usually is). The equation describes multiplicative gain, as in the case of capital accumulation. This is why capital in hands of few people, like billionaires, is so dangerous, because it grows exponentially, until they will have all, and the others nothing, like in the monopoly game. On the other hand, many gains, like muscle gain after exercises, are rather additive in their nature, thus they do not grow so spectacularly. I started to think about it after posting this meme, now I am not sure whether this is upsetting or inspiring 😁
