Brace yourself for a sudden rush of jealousy, because Chinese publisher, the Hurun Report, has published its list of the richest people on the planet. So who makes the top ten, and what did they do to get there?
And where is the billionaire's capital of the world?
The study found that Moscow has taken the title of the billionaire's capital of the world - with 76 billionaires. In second place is New York, then Hong Kong, Beijing and London.
Yet the vast majority of the world's richest billionaires shun the bright lights of these cities. So who are the ten richest people on the planet, where are they, and how did they make their money?
1. Carlos Slim Helu and his familyThe Mexico City telecoms mogul is worth an estimated $66 billion - making him the richest man in the world.
His money originally came from his telecoms business, but he has since built an empire spanning everything from mining and real estate to newspapers and football clubs around the world.
2. Warren BuffettThe man known as the Sage of Omaha is said to be worth $58 billion - made from his investing business - which has also made countless other millionaires.
3. Amancio OrtegaThe retail giant from La Coruna is worth $55 billion. His global fashion company Inditex lay behind the fortune.
He stepped down in 2011, and has since made an extraordinary range of personal investments - in everything from a skyscraper in Madrid to a stake in a horse jumping circuit and a hotel.
4. Bill GatesMicrosoft made Bill Gates an incredibly wealthy billionaire, who is said to be worth $54 billion. However, nowadays he is best known for his charity work. His foundation has become the largest transparent private charitable foundation in the world, giving billions of dollars to support international healthcare projects.

8= Charles and David KochThe first men of inherited wealth in the list are worth $31 billion each. They inherited their father's business - although in their lifetimes they have increased the size of the business by thousands of times. The brothers are involved in businesses ranging from chemicals to oil refinery and toilet roll. They also give hundreds of millions of dollars to charity.
