U.S. Customs. Why do I never pay customs?

He said he takes home around 1/3 of what his employer pays for him. He -didn't- say that he pays 67% income tax. What do I mean?

When I first joined the workforce (USA), I was told that for every dollar my employer paid me (before taxes), they had to pay another $2 out. Things like unemployment insurance, insurance coverage to cover me while I'm on the job, the 1/2 of my Social Security they must cover, the cost of paying someone to do payroll amortized over all the employees. Stuff like that.

Maybe that is what he means.
