Female Workers Have Short Career Span At Industrial Zones

This is source I found from another site, main source you can find in last paragraph

Now, with the advent of the industrial and medical revolutions, suddenly there was surplus wealth (to pay for schools, social programs, safety nets), machines that equalized strength, education to give both genders a chance at contributing to society and longer human lives to fill our cities. With this, the necessity of having babies to preserve society diminished. The need for strong and durable men to work in fields, factories, and in war began to diminish because machines did the "equalizing" work. This has continued apace even to today, in places where machines do ALL of the heavy lifting and all that matters is brain power. Now, there may remain a few select jobs where brute physical strength is at a premium (front-line soldiers, miners, construction, etc.) and those are likely to continue to be dominated by men for obvious reasons.
