Samsung. It grew up to be a chaebol, merely because of the support from fascist dictators(박정희, 전두환). It still is deeply connected financially and politically with the conservative politics(박근혜, 윤석열. You can see Samsung was the one loyal patron of Park Geun-hye regime). With the wealth from the dictators and from corruption, it is still exploiting the workers. As I remember, workers’ union(삼성노조) was allowed by the company only one or two years ago.
