It is unclear how more women in the work force is a good thing - but usually something about "empowerment" and "improving the economy" is muttered.
However, the data has shown that increase female participation in the economy has not grown the GDP or increased wages. Prior to women entering the workforce in mass, it was common for a man to be be able to provide for a household. Now it is frequently necessary for both the husband and the wife to work to make ends meet. The small children are typically raised in day care by strangers.
This is obviously just a simple case of supply and demand. And more people enter the workforce, the supply of labor increases which lowers the wages: http://www.ramzpaul.com/2017/10/ivanka-pushes-female-empowerment.html
