For some, some of us would love to see more equality in the workplace. As an engineer, I would love to see more women, this place is a sausagefest. Ideally, most jobs should have a ratio comparative with the population at large, that fact that coders and engineers are fairly well paid (well, except me) makes it even more important for generally equal representation.
However, I am also convinced that much of this is a bunch of rich assholes who see the 70-cents-on-the-dollar statistic and say, we need to hire some more of these cheap women, only to find that there aren't that many in the field. Same with the push to get the markets saturated with cheap coders any way they can so they can systematically lower the pay of programmers in general.
