Exactly. My wife makes almost as much as I do. Cutting our income in half so she can stay home with the kids is not a viable option.
I made the same as my husband when I quite working.
We both have degrees in computer science.
We had more expenses than most because we had sick twins. We had diapers for two $100/mo, special formula for two $400/mo, and then when they were two they both needed speech therapy that insurance didn't cover, $300/week.
My twins are now 8, and we just bought a larger house. Some people couldn't believe we could afford the house. I knew it would be easy because we don't have the expenses that we had when they were little.
I quit working when my son was a year old. I had miscarriages before I had my son, and we wanted to try to have another baby. I thought I would be going back to work after I had 2nd baby. Then I had the sick twins, and the doctors told us daycare was not an option. Then we found out that one of the twins had brain damage.
I'm glad I never went back to work, and we managed on one income. Now it's much easier (and we still managed to save money).
