Let’s do some math here.
Of the top 10% richest people in the world, (8 billion people live in the world, (10% of that number would be 800 million) Half live in Singapore? So 400 million of the richest people on earth live in Singapore? What are they now the 3rd most populated country on Earth now? I thought the USA was 3rd.
Wait…..only 6 million people living there? Do you see a problem with the math here?
The below link shows the number of billionaires per country. As you can see the USA has the most followed by China, and Singapore is number 20 on the list
