I don't think families can earn enough money with one wage-earner any more. I also think there are a lot of men who don't want to bust their butts and do that kind of work. They want to stay home with the kids, but guys who do want to do that aren't looked up to as the masculine kind of guy, and that's a shame.
I feel a terrifically painful disturbance in the natural law of things between men and women that must be balanced in the next few thousand years. What has been done in the name of holding up masculine energy as God and feminine energy as subservient has really wiped out everything.
