This maybe true for men but women actually we don't want to spend our life doing all that and looking after you, the kids and your mom.I understand yours and my parents probably got one of the shittiest ends of the deal, (born into war-torn country) but LOL it's not because they don't want to be a slave to man, get over that shit!! (are you even aware the last Korean President was a woman?)
I'm sure you're aware of how Korean society plants these ideas, ever since at a young age, only way to be successful in life is to go to college and work for some corporation, or become Doctors, Lawyers, Engineers, etc...
12 year old Korean kids schedules are like 7am go to school til 4pm, then go to some extra curriculum activity usually consisting of (playing instruments or some special skill), then go to after school study program, learn English, Chinese, Japanese, study more until like 10pm, then get to come home and probably study more, sleep few hours and do it over next day is the reason for highest suicide rate among teens out of any first world country.
Then you're lucky if you get accepted to college, if not, you gotta do 재수 (repetitive study of college exam) until you make it. If you're male and turned 19, you gotta drop everything and go do your mandatory military service. Then say, you made it all the way, and graduated college and got hired at some corporate job.
Your life is over. All of my friends, cousins, people that I know who works in Korea, male or female, all are prisoners of their job. Everyone on salary pay but work your ass off without overtime and if you lack in putting your time in, next hungry guy/gal in line is going to take your place so there's no choice but to work. In the midst of this harsh lifestyle, there's no time for dating, relationships, marriage, or even thinking about having kids.
Don't you think it's weird when you watch Kpop culture, so many Koreans are super talented but they never come up with anything original. That's because Koreans value skills and technique over creativity and thinking outside of the box.
This institutionalized lifestyle from birth to death is the reason why they don't think too highly of getting married or having kids in the first place. What the fuck is the point? Just going to work til you die...
Heavy burden of domestic duties and inlaws was the number 1 reason women divorced. Since this is about why women don't want kids I think you need to consider these views that you may not consider being a man.
