World woefully lacking in female self-made billionaires

Consider these disappointing statistics:

Of the top 10 wealthiest women in the world, every single one inherited their wealth from a male relative.

Of the world's 1,011 self-made billionaires (those who made their own money rather than inheriting it), only 14 are women.

What do you think is the reason for this huge discrepancy? Is the business world still stacked against women? Is it because most women are adverse to the idea of being extremely rich? Do women care more about "the mission" than making a lot of money? What is holding us back, and how do we get beyond it?
