Realistically, it's nearly impossible for high income young people in their 20s and 30s to buy a house in Seoul. That forces them to move to the provinces, but then there's almost no infrastructure. No companies either.
So many people turn to leverage in hopes of a life changing reversal.
The recent rise in the KOSPI index happened because some of the loopholes that Korean conglomerates used to make inheritance easier were blocked by revisions to the Commercial Act. One of the uncertainties that had been called 'Korean risk' was removed, and the market went up.
For a Korean man, the moment you leave Seoul, not just the outskirts, but out of Seoul entirely, there's no one to talk to about IT jobs. I live outside Seoul, and the infrastructure gap is about 10 to 20 years behind. On top of that, there are no IT companies, just mostly low income manual labor jobs.
The median monthly income for Korean men is about 3 million KRW, while the average Seoul apartment price is 1.3 billion KRW and the median price is 997 million KRW. That means you'd need to work for about 25~30 years just to buy a home, but job tenure is getting shorter, so that's not realistic.
So people gamble on leverage, hoping for a life changing win. Everyone around me knows it's gambling, but they figure they're already in a dead end situation anyway, so they have nothing to lose.
I live and work in IT outside Seoul, but the IT business has already matured, and there are many well established companies. The Korean market itself is small, so early movers have already taken the lead. There's no room for latecomers like me. That's why I take on work from the West, China, and Japan regardless, but even that's hard without a reputation.
The moment you leave Seoul, a Korean's chances of success drop to nearly zero. That's why people cling to the city so desperately.
And honestly, I've hardly gambled on my life. But I'm drowning in debt, and sometimes I feel like a fool for working so hard.
