Again, I agree.
I've always held the belief that it is possible to run a family on one income. The problem is, when you have two couples heavily immersed in the rat race, they're working to support a lifestyle, not just run a family.
My wife is a Stay-at-home-mom, and my salary (high 30K range) is enough to suit us fine. Granted, we don't take vacations in hawaii, or weekenders in the Hamptons, but we have a very close family because of it.
