Musk rebuked the United Nations: If it proves that $6 billion can solve global hunger, sell shares and donate money immediately

Musk, the world's richest man, unceremoniously rebuked a U.N. official who said he could help solve global hunger if he donated a fraction of his wealth.

Musk responded on social media to David Beasley, the director of the United Nations World Food Programme, who earlier last month called on billionaires like Musk to "stand up and give a one-off help," a call that was repeated last week.

Beasley named Musk and Bezos to take action, both in the top two of the Bloomberg Billionaires Index. Beasley said that just $6 billion could save 42 million lives worldwide.

Musk responded on social media that if the World Food Programme can use transparent and open accounting methods, "here to explain how to solve the problem of global hunger with $6 billion, I will sell Tesla stock and donate money."

$6 billion is only a dime a dozen for Musk. Last week, Tesla's market capitalization topped $1 trillion. According to the Bloomberg Billionaires Index, Musk's current net wealth is as high as $311 billion, an increase of $9.3 billion in a single day on October 29 alone.

Tesla accounts for a large part of Musk's net worth. He rarely sells Tesla shares, which as of Friday had reached a record $1,114.

Musk, who often goes out of his mouth on social media, has been critical of the U.S. government's plan to tax billionaires.

He tweeted that taxing billionaires was a drop in the bucket for paying off the country's debt and that authorities should focus on cutting government spending. The introduction of a billionaire tax is just the beginning of a tax on the wider affluent.
