Our company taps into top-tier stay at home moms regularly for all kinds of consulting work.
This lady's a whack job, but her point is valid. You don't need to go to work to maintain some sort of connection to your career, and you can do it in the context of staying home to raise your kids.
However, don't expect to CLIMB some sort of ladder while you are raising 0 to 5 year olds.
The technology available in the home is MOST DEFINITELY good enough for great talent to contribute in specific ways. We get talent we couldn't even discuss affording at incredible rates simply because we accommodate stay at home moms.
In large organizations, this is a nightmare. Small to medium, this is very workable.
And this is a good situation for people and companies. What if I don't need 40 hours a week for someone to be a high paid employee but instead I need about 50 hours per month? I can get a talented person for reasonable cost and she gets to earn income and maintain her skills and sanity doing grown up stuff on the side.
