have been living in both countries.
--消费水平，everything is much more expensive, such as Chinese food,
restaurant, appliances, house, car
--医疗，you may need to pay more for medication as it is co-pay in US
--上学（儿子三岁），similar for primary & high school, but much cheaper for university
--人的友好程度，much nicer
--退休生活，为将来未雨绸缪，would be similar for someone with 401k in US and with super in AU
--工作机会（我需要找工作。我是医疗技术人员）: I still consider it would be easier in US while the unemplyment rate is in history low at the moment
--自然环境，much better, I would consider it is the best! when I went to US 10 years ago, my supervisor said nowhere better than Sydney
--STRESS LEVEL，low
--开车，（和美国反方向？）it won't be a problem, you'll be okay in a few days.
some difference in house: you can claim tax deduction for the interest from the house you are living and it is not the case here;while you can claim tax deduction for the interest from an investment house and it is not the case in US. house price here is much higher than US.
