Which is the best to immigrate to the United States, South Korea and Britain?

The United States is good, the prices in the United States are cheaper than those in Britain, and Americans are not as rigid and tolerant as Britain. The population density of the United States is higher than that of Britain, the house price is lower than that of Britain, and there are more formal places to play, because the population density is lower than that of Britain, cars are cheaper than that of Britain, and the price of South Korea is about 2-3 times higher than that of the mainland. It is not easy to find a job in Korea. Many enterprises are chaebol, and it is not easy to get in. South Korea has sedan chairs because people often commit suicide by diving, while the United States is a multicultural country, an open, enthusiastic and free country that pays attention to creation. If you have great ability, you will have a good development space in America. Britain is an old capitalist country with a rigorous tradition, and its trained talents are very gentlemanly and elegant. Korea is hands-free.
