The United States has ~4.25% of the world population, but 8 of the 10 richest people in the world live in the United States.

Even if you just take the advantage of being born in the United States (which, fine, exclude Musk from that list then) 7 of the 10 people on the list, including Zuckerberg, are among 5% "luckiest" people in the world just based on where they were born.

This is eliminating any luck they got from hereditary wealth, geographical location, and catching the surge of value in their respective industry at the exact right time.
