This is not true for all women. Some women stay more at work than they stay at home while there are men who work from home. These men spend more time with their children at home. Times have changed, and it is no longer women always staying at home while men go to work. Both sexes go to work now. Whichever parent stays at home should be a decision both of them should come together and make.
You are right but you will agree with me that 60% of women in the world today spend more time at home with their children than men because men are seen as the breadwinners in the family so they are always not seen at home with their children unlike the women who have more preferential treatment even at work than the men who may experience more late time in closing from their workplaces.
Do you have any statistics to back up your claim of the 60 percentage you have there or it is just another assumption of what you think is happening? Did you conduct any interview or survey to determine that? Even with the figure, I guess you are only referring to the underdeveloped nations because in first world countries there are no gender barriers. Everyone who can work earns and are breadwinners. This believe of women not working was the case in Africa ten years ago when our mothers were called housewives. Today, it is not that way. Most women now have paid jobs they leave their homes to do. And most of these women are now breadwinners too.
