I agree with you regarding workplaces. Mixed work places are much more enjoyable places to work.
It's interesting to consider your suggestion that if women had been working for the last 100 years technology etc might have developed faster ...
Having more people working would increase demand for some services and products, but would it increase enough to support wages for a doubling of the workforce?
Does doubling a workforce double the rate of progress? E.g. if twice as many people worked on the space program would we have people living on Mars by now? Or is there a leveling off where the increase in progress slows as the workforce increases?
With modern appliances and materials, a week's housework can be done in about 4 person hours. But before the middle of last century running a household was hard, slow work. Would it have been sustainable for both adults in a typical household to work?
I suspect there are a lot of men similar to myself who may be sick of working in one-sided male dominated environments and who would like to see their chosen field become better as I am sure it would by including people who are different. I can only imagine what the world would be like if for the last 100 odd years we had included the other 50% of the population as much as it could have been - what great inventions, software applications, hardware, technologies, video games etc. would there be if we had seized about the possibilities that diversity and inclusion and equality gives us.
