While we can't really answer that question, we have a feeling a trillion dollars would be more than enough.

The world's first trillionaire

Jeff Bezos, the guy who founded e-commerce site Amazon, will likely become the world's first trillionaire in 2026, business software comparison site Comparisun predicts.

The prediction is made based on Bezos's average net worth increase in the last five years, which is 34 per cent, and his current wealth.

Basically, if his nett worth continues to increase by 34 per cent on average, Bezos will become a trillionaire in 2026 at the age of 62.

That's 1,000 billions, in case you're trying to wrap your head around the figure.

It's hard to imagine someone who is already earning an average of USD2,489 (RM10,819) per second earning even more than that in the future when there are so many struggling to live in a world where wealth disparity is becoming wider.

Jeff Bezos is often in the headlines not only because of his businesses, but also for many other reasons - both good and bad.

In April, he donated USD100 million (RM434.5 million) to food banks in the United States to help those affected by the COVID-19 pandemic.

Sounds like a lot of money, but according to Business Insider, for Bezos, spending USD1.3 million (RM5.64 million) is like spending USD1 (RM4.35) for an average American.

A heartfelt THANK YOU to Jeff Bezos for your generous donation to Feeding America, all of which is being provided to network members including Treasure Coast Food Bank to support food purchase and distribution through May 12, 2020. #grateful #FeedingAmerica @JeffBezos pic.twitter.com/TTyLw2wKjJ

Which is to say that Bezos has so much money that the amount he donated is peanuts for him, plus he'll likely get tax relief from it too.

Just a few days after he made the donation, one of Amazon's vice president Tim Bray quit his job over the firing of Amazon staff who were making noise about warehouse staff being afraid of COVID-19.

According to Amazon, it has spent more than USD800 million to keep its warehouse staff safe.

Bray, in a blog post announcing his resignation, said that he believed that Amazon has been taking measures to keep it's staff safe but he also believed the workers who voiced their concerns.

"And at the end of the day, the big problem isn’t the specifics of COVID-19 response. It’s that Amazon treats the humans in the warehouses as fungible units of pick-and-pack potential. Only that’s not just Amazon, it’s how 21st-century capitalism is done," he wrote in the blog.

He also details other issues with the company in the blog post.

Others are not far behind

Although Comparisun expects Bezos to become the first trillionaire in the world, there are a few others who are not too far behind.

Chinese real estate developer Xu Jiayin is expected to earn his trillion the year after Bezos, in 2027, followed by Chinese business magnate, investor and politician Jack Ma in 2030.

Facebook founder Mark Zuckerberg may take 10 years longer than Bezos to earn the title of trillionaire, but he is expected to be the youngest person to do so at the age of 51 in 2036.
