I am absolutely fed up of being the sole bread winner in the house. The kids are 7 and 9. I am frustrated that my Wife keeps saying she needs to not work and stay at home to take care of the kids. The kids go to school and we have a part time maid who comes in twice a week. How do I get her to go back to the workforce instead of sitting at home and spending all my hard earned Money?

I am sorry you feel this way. I think you really should sit down and have a heart to heart talk with your Wife and tell her why you want her to go back to work. There is no use bottling up such emotions. You are clearly frustrated and that's okay, but do understand where your dear wife is coming from when you speak to her. You can also suggest to her to start exploring the workforce by doing part time work like telemarketing, writing etc. There’s a great website / organization called mums at work that you can look into.
