I was born in South Korea so I keep track of what goes on in Korea. Frankly, I don't like much of what goes on in Korea. Korean economy is much stronger than when I left back in 1976, but corruption still reins strong at all layers of Korean society. A clear indication of this is that salary level in Korea is substantially below its spending level: people making $3000 a month spending $1000 for a night of entertainment. A son of current Korean president is said to have spent $200,000 a month without a clear source income and hid boxes of money in his balcony.
Time is on your side
Some of the corrupted get caught, typically before and after the political rein changes hand. When the eyes of law focuses on you in Korea, time is on your side because attention span of Korean people, politics, and law is short. If you need some extra time to manuever your way out, you check yourself into a hospital to buy time. If you need more time, you need to leave the country. Your destination is likely to be US. A former head of IRS in Korea, accused of threathening conglomerates into donating money to a presidential candidate, now lives in US. The candidate he backed lost the election five years ago, but now the candidate is most likely to be the next Korean President. Time is on your side if you are corrupted. Korean People forgets. Korean Law forgives.
Some crimes in Korea are unforgivable and unforgettable. Every Korean boys and girls learn the name Lee Wan Yong from early on. Lee Wan Yong betrayed the country to Japan in the 19th centry and his name lives on. His descendents live in hiding even now and will never be able to leave the shadow of their famous ancestor, not even after a thousand years.
