Why did emphasis on gender roles re-emerged after World War II?

cause they said women cant fight in war, and they had to stay home with kids (not sure if this is right sorry)

Explanation:

during the war- With men away to serve in the military and demands for war material increasing, manufacturing jobs opened up to women and upped their earning power. Yet women's employment was only encouraged as long as the war was on. Once the war was over, federal and civilian policies replaced women workers with men.

Explanation:

after the war- the war changed the lives of tons of  women and men in many ways. for exmaple, Wartime needs increased labor demands for female workers, more men died, so more women becamed widowed, and sometimes got to keep husbands property. this soon heightened domestic hardships and responsibilities, and intensified pressures for Americans to conform to social and cultural norms.
