Median Household Income (2013):
US: 52250 USD
Singapore: 7870x12 = 94440 SGD (=74952 USD, USD/SGD=1.26 at the end of 2013) (=68934 USD, USD/SGD=1.37 now)
GNI per Capital
为方便计算,假设美元对新币1.33. 年收入一样US$75000, S$100000.
美国
假设一个中上收入的专业人士拿回他交的税的fair share (24% social security + 24% medicare), 那他实际交(11968.75+5737.5)*(1-48%)=9207.25 (S$12245.64). 当然这个假设是不成立的,因为"Social Security benefits are heavily biased towards lower salaried workers"。所以实际上交的税大于9207.25.
州税大部分用在教育和医疗(82%),假设每人拿回全部没有交州税。
新加坡:
所以在美国比在新加坡至少多交S$ 12245.64-5650=6595.64的税。
