I like here because it's safe, affluent and not much pollution and I love the fact that there is no traffic here. But if I am a foreigner it's hard to find my ethnic food and supplies where as in Los Angeles no matter where you are from you can always find your food and stuff you need. People here are fine and polite, schools are good and houses are cheaper. I like living in US, right now at my age because it's more peaceful, quiet and heathier. Hong Kong is more for young people. Tax and medical are not my issue. If you work, your company can provide you good insurance and benefits. If you're really poor, there's a lot of government assistance for you. Regarding discrimination, as long as you can communicate and fit in the society and go along with the locals way of living you wouldn't face prejudice
