Its not like on June 15th, 1978 women were suddenly viewed and treated as equals as executives, it just started there.
To the above poster, I wasn't trying to start a shit storm and I don't know why there would be one. I was just pointing out that there are some obvious reasons behind the stats. I didn't know this would be controversial...what is the opposing view that you're trying to state? That women just aren't as capable in business?
I think there are various reasons, and probably a lot of factors play into it. Women are probably less likely to take risk, too-- and since a lot of business ventures are risky this could play into it as well. Women may also have on average, a different definition of success?
But I was also thinking about the fact that there is a lot of old money out there. Traditionally in very wealthy families, the sons (if there were any) worked for the family business and would inherit or take over the company when there time would come. There are probably quite a few men on the list who inherited money, and then built upon the wealth.
