The 20th century billionaires vs modern billionaires

There is also a significant gap when compared to the current top five living rich people. Cumulatively the top five modern wealthy people have a net worth of $514.4 billion which is at least three times less than the 20th century top five richest people.

The group is led by Amazon (NASDAQ: AMZN) founder Jeff Bezos with a net worth of $125.30, followed by Microsoft (NASDAQ: MSFT) founder Bill Gates who enjoys a fortune of $112.60 billion.

In third place, Bernard Arnault of LVMH Moet Hennessy Louis Vuitton with a net worth of $108 billion. Head of Berkshire Hathaway Warren Buffett occupies the fourth spot with $90.40 billion while Amancio Ortega of Zara fashion closes the top five group with a net worth of $78.10 billion.

A review of the wealthy in the 20th century shows that the group was evenly distributed across the world. However, the current list of the top global billionaires is dominated by Americans. Sadly, when both groups are compared, no woman has made a cut.
