I would also bet that many here think that South Koreans coming to the States are the same as Mexicans seeking a better life here. To be honest, to the average Korean living in and around Seoul, (almost) any place in the US would be a significant downgrade. I have been to places in Asia (Beijing/Shanghai in China, Seoul in South Korea) and the Middle East (Dubai, Abu Dhabi) that seem like something out of Star Wars.
There is a reason all but one of those South Koreans decided to go home even as the President gave them a chance to stay. The one who decided to stay did so because he had family here.
As I mentioned earlier in this thread my Korean American girlfriend has told me that Koreans are outraged by what happened. She says that it’s caused a substantial anti American feeling in the country. I also stated earlier that she,a US citizen and a huge Trump supporter,is also angered by this incident.
