Now I'm on very thin ice and just based on youtube videos so if someone from South Korea reads this feel free to correct me.

As I understand it the order of things for men* in SK is 1) housing 2) marriage 3) children

No housing means no wife means no children to afford a nicer home. So, they're incentivised to take big risks.

But I'm going to step out of this minefield now with the hope of someone who actually knows things providing some information. It just seemed like the original comment didn't give enough weight to context.

*Women in SK are as I understand it fighting a whole other battle.

That seems the same as anywhere else in the world where women have the option to be independent. It even applies for many other species.
