That should give you an idea of the power of the Chaebol in Korea. They can be absolutely brazen and still get away with it. In the U.S., there is still a line that cannot be crossed.
Lee Gun Hee's first presidential pardon came after a conviction for bribing the President of South Korea. Can you image if irrefutable evidence emerged that Tim Cook had given bribes to Barack Obama (direct quid pro quo, not campaign contributions)? His next presidential pardon came about 10 years later when he admitted publicly to tax evasion and embezzelment, so it was an open and shut case. CEO's have a lot of power in the U.S., but it is on another level in Korea.
