The scale of their wealth
Health
The price of life
Let's compare Robert Ziff's fortune with the healthcare spending of a massive country
Robert Ziff could fund the entire healthcare system of DR Congo, with a population of over 105,800,000 people, for approximately 3.2 years.
But even if we compare their fortune with that of a rich country
On the other end, Robert Ziff could cover the healthcare spending of Luxembourg, considered the most heavily funded healthcare system in the world, for 1.4 years.
Education
Buying the future
Let's also compare their fortune with education spending, first with a poor country
Robert Ziff could cover the total cost of Nigeria's education system, the most populous country in Africa with over 243,000,000 inhabitants, for 2.1 years.
And yes, we can also compare it with a rich country
But they couldn't just cover the cost of a poor country; Luxembourg is considered the country with the highest per capita investment in education in the world, and Robert Ziff could pay for it entirely for 2.9 years.
Research
The monopoly on progress
Coming full circle, we think it's also interesting to add another gigantic country
Robert Ziff could fully fund the state research budget of Pakistan, the fifth most populous country in the world with over 260,000,000 inhabitants, for 12.1 years.
And of course, the country that invests the most per capita worldwide
But even if we compare the total wealth of Robert Ziff with Israel, the country that invests the most per capita in research in the world, they could cover the total cost of the system for 0.3 years.
Gold
Everyday luxuries

Robert Ziff's fortune is equivalent to 49 tons of gold. It's hard to process, since we don't usually keep a handful of gold bars in our piggy banks.

A standard gold ring usually weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18 karats.
Based on today's gold price (excluding the jeweler's commission, shipping, or anything else), that ring would be worth $546.86.
Robert Ziff could buy 13,145,584 gold rings. That's a lot of fingers and way too many gifts!!
And if you're struggling to visualize that many rings, it would take 2 trucks to transport them. Although Robert Ziff will almost certainly have enough money left over to pay for the gas.
Biography
Like his billionaire brothers Dirk and Daniel, Robert Ziff owes his fortune to his grandfather's publishing company, Ziff Davis.
The brothers' late father, William Jr., built up Ziff Davis, publisher of PC Magazine and Car and Driver, and sold the company for $1.4 billion in 1994.
The brothers created Ziff Brothers Investments and grew their inheritance with hedge funds in the U.S. and in London.
Ziff Brothers Investments ceased operations in 2014; the brothers are reportedly investing with former employees of their hedge funds.
