How did WW1 create new opportunities for women and minorities?
The exodus of men into the armed forces and the economic boon that is caused by war resulted in huge job vacancies. Women and minorities filled positions that were not (for the most part) available to them prior to the war.
somebody had to fill in for the MEN that went off to war at the factories and that .
It was more WW2 that had a significant impact for women & minorities. It was as blynken stated.
