This is fatalism and societies that adopt this attitude fall into some nasty traps. For example, there's no point to solving problems because it's the will of God.
It's not fatalism. It's about recognizing that a more economically even society is warranted because people shouldn't get outsized credit (or be disproportionately punished) for things outside their control.
Real life is complicated. Who decides what is in their control? What if it's a combination?
Society gains incredible wealth from the desire to gain outsized credit for those we care about.
Economic evening can quickly become a poison.
It seems like more of a philosophy of humility than fatalism.
