Are women too sensible?

At the recent Telstra Business Woman of the Year Award Luncheon, the usual dismal stats on the number of women in key government and big business positions were trotted out.

Here's an alternative take:
What if most women are simply too sensible to WANT jobs in these positions?
What if most women PREFER active contribution to playing the zero-value empire-building and ego games in the hot-air heights of big business and government?
What if most women actually want to DO good stuff instead of just talking the part?

Has anyone done any research into this? Has anyone asked?
