And the running discussion over there is that Hyundai owns Boston Dynamics so they expect all their jobs to be replaced by either AI or Robots in the coming years.
In fact, the parents often actively enable and support this strategy. Unthinkable in the West.
This is nothing like "I sent 300 resumes to every place in the country and can't get a job". Of course, such people do exist, but those are in majors/fields in which it was already near-impossible 10 years ago to get a job in most of the world. If everyone in Denmark would go "Maersk, Novo Nordisk, Carlsberg or bust", you'd see the exact same.
Honestly, your story indicates that your sister-in-law and her friends are likely at least middle class. Those who simply can't afford to sit around for 2 years (lower class) do just get a job straight away.
But really, being deeply ingrained into society and having personally worked at such places here in Korea is worth more than flawed statistics, which really all statistics are when it comes to these topics. I've literally personally interviewed the very few applicants we got as a small company outside of Seoul. They didn't know the difference between a GET and a POST; these were people applying as a backend API developers. We had to train people from absolute zero. And this was at a "modern" workplace ran by young leadership, which should theoretically be much more attractive - one of the, if not the number 1 most commonly named reason for not wanting to work for smaller companies (and even moreso outside of Seoul) is "old(-school) working culture".

These companies aren't like Silicon Valley startups abusing H1Bs, hiring foreigners because they're cheaper, Koreans genuinely aren't applying.
Go ask her and her friends how many 중소 outside of 수도권 they've applied to. Again, if they've studied something like German language or archaeology then sure, but people aren't getting jobs in those fields in Sweden (to name a completely random high HDI country) either.
I will say, her friend group is my only sample, but my general understanding is that it's even hard to get a job at olive young these days, maybe they're misleading us and are lazy tho, that could be true.
