It happened just not in the way we anticipated.

Women went from carrying washboards to the rivers edge to walking downstairs and dropping a load into the washing machine. Root cellars became ice boxes became refrigerators. Instead of beating the rugs you run a vacuum, etc.

Women could've hung out at home with this newfound time, but instead they mostly went into the workplace. This roughly doubled the labor force and over time essentially halved wages workers took home, making dual income households the norm and now essentially a requirement to own property.
