Who is the richest man in the world?

 

Again, Microsoft founder Bill Gates has topped the list 16 of the past 21 years, including the 2015 list. In 2015, there was a record of 1,826 people on the list that included a record 290 newcomers with 71 from China, 57 from the US, 28 from India and Germany with 23. People under 40 had 46 join the list. A record of 197 women were on the list.

He would have been way richer than Carlos Slim, who is ranked second richest but he donated about 30billion to Melinda foundation for charity.

Could he has topped for so long because of the values he adds to the world? Could it be the principles of giving and multiplication? What do you think?
