Okay, as a Korean, I would just like to chime in and say that Samsung is much more than a smartphone/digital gadget company. It’s a very big company. It not only produces displays and semiconductors, it also makes home appliances, it builds apartments, it runs hotels, it runs hospitals, it issues credit cards and runs insurance, etc... which means that the Galaxy Note 7 crisis is pretty much nothing to that gigantic…
Can you go more into why you aren’t positive about Samsung?
While there are these mega-companies in RoK and Japan that have especially "close" relationships with governments, I don't think it's that dissimilar from the revolving door of lobbyists/board members/politicians in the US. Citizens in the US are similarly critical of corruption at this level in pharma, tobacco, military, etc.
At the same time, these companies are all responsible to varying degrees for the success of the economy and first-world lifestyle in the US, Japan, RoK. So you can't just want them not to exist either.
