This seems paradoxical, but I believe it's less likely in the USA becasue our companies are less "corrupt".
What I mean by that, is Samsung is so big it's like a feudal kingdom. There aren't clear lines between the government, other aspects of life, and samsung. That means any sort of power stuggle has to involve all those different aspects. The head of samsung stands in the way of ambitious people in the whole society, not just ambitious people in that company.
Compare that with the USA. If there is a power struggle in a company you don't have to attack the head person with such intensity to advance yourself. It's even possible to advance by moving to another company in the same industry.
