Tim Noah写道，1999年到2008年之间，雇主承担的健康保险的保险费增加比工资增加快了6倍。
Between 1999 and 2008, employer-sponsored health insurance premiums increased six times faster than wages, Tim Noah wrote.
保险费也增加了。
由于保险费随承包范围变动，如要增加投保险种，则额外保费应由买方支付。
Since the premium varies with the extent of insurance, extra premium is for buyer's account, should additional risks be covered.
