So what time period are you specifically focusing on, just so we are clear. Because right now it seems like you are being vague about that just so you have the ability to move the goalpost as needed. 

If you're specifically talking about WWI and WWII, then I wouldn't be here if women didn't keep civilization running while the men went off and shot each other. 

Side note, I dont exactly remember, but I'm pretty sure I came out of a woman, so I am the product of a man doing 5 minutes of work and a woman doing 9 months of work.
