We live in an era where engineers can earn more than the President

The President's annual salary is around 250 million KRW, right?
But for production workers at Samsung Electronics or SK Hynix (including next year's expected bonuses),
it seems they earn over 600 million KRW.
It's a great world to live in!!!!!
I heard the average annual salary for people in their 30s is around 50 million KRW.
