As per Google search these are the top 3 richest person of this world.
1.Jeff Bezos $108.9 billion
2.Bill Gates $91.9 billion
3.Warren Buffett $90.1 billion
But these maybe wrong since in this world there are lot of blackmoney is available which were not recorded by any governments.
In my opinion the politicians from the third world countries can be in the richest persons because they were stealing all their country's taxes.
May be true.Many politicians in third world countries had earned lot of money in illegal manner.We don't know anything about their earnings.One real fact is we don't know the real richest person in this world.The richest person is the person who had highest profit in his account in legal manner.They had earned this profit by paying taxes.My point of view is,we can't predict the real richest person in this world.
