Was the feminist movement really liberating?

I recently given The Myth of Male Power by Warren Farrell to read, and although I do not totally agree with his assessment of masculine/feminine roles in society, one of his premises is this: The feminist movement sought to provide women with opportunities for careers outside the traditional “womanly” careers, such as home maker, nurse, secretary, etc. While there has been much progress made in this area, as the old saying goes, there is a long way to go, especially in providing equal pay for equal work.

This is the evolution as I see it:

The Old Standard: The man would typically have the career outside the home providing enough income for the family to be upwardly mobile; the woman would stay at home, raise the kids and manage the home.

The Ideal Standard: The man and/or woman would have a career outside the home, each having the same opportunity to provide an upwardly-mobile lifestyle; home-making duties would be split up and/or outsourced to nannie/daycare/etc. This would provide a choice for the couple.

The New Standard: The man and the women have jobs (not necessarily careers); economy has evolved to require the incomes of both parents. Outsourcing of childcare is a requirement, not a choice.

What is the cause of the change from the Ideal Standard to the New Standard?
