for what it's worth the salary of a mid-level manager in India is half of what an equivalent position will fetch in Korea (this surprised me greatly at first).
with South Korea's GDP per capita being 10x that of India, I would've expected a more than 2x difference. So this would imply a much lower difference between manager and worker incomes in Korea than in India. Basically Korea's better social equality smooths down what should've been a 5x-10x difference to a mere 2x one ...then again, my understanding of East Asian economies is not very good, and they are know to be economically "weird", so I may be quite wrong on this.
