It wasn't long ago that South Korea wasn't so advanced, and Daewoo was corrupt.
The national identity has been trying to raise standards in everything, but it still has horrible reminders of its recent past. The Sewoul disaster where hundreds died needlessly, the subway crash where 200 people died, the recent collapse of a sidewalk grate where 16 concert goers just... died.
By "national identity" I mean the health, safety and anticorruption standards are considered part of the national identity and distinct from the standards of many neighbouring countries.
In the past 20 years Korea has been rebuilding everything and has good standards. These stories are making the country obsessive over safety and quality, but there's still junk from the recent past, or people who are wrapped in nepotism and corruption who shouldn't be responsible for anything involving public safety, but can't be removed.
As long as the ship builders are not part of that past, then it's a boon for the country and another milestone for Korea's advancement.
