Snopes article on the “emerald money” story. TLDR, “A story about Musk’s father once owning an emerald mine evolved into a larger rumor that had no evidence to support its central claim.”
Musk’s first company was Zip2, which he co-founded with two other people and $28,000 of seed capital from his father.
i mean, that’s still way more wealthy than most people. i don’t think i know anybody who had 28,000 buckaroos of money to burn on their child’s business venture. and the article that you linked does say that musk’s dad made around 400,000 dollars off the emerald mine, which is… still more wealth than most people will see in their lifetime. according to Errol, he sent money he made off the emerald mine and by selling his yacht to Elon and Kimbal to pay for living expenses while they were studying in the US.
It’s not easy to become a billionaire from 28,000 USD. Definitely not based on luck alone if you grow several businesses.
Most people don’t get seed money from their parents, but the median American will inherit $70K from their parents.
Regardless, most people who start a business can take out a loan. And to put things in perspective, even opening a fast food restaurant will require over $200K.
In other words, the advantage that $28K gave Musk was nowhere near enough to open a small restaurant, much less automatically turn him into a billionaire.
