Somewhere between 65 and 75 percent, anyway. Herd to pin down.
Somewhat arguable since some of the FICA and Medicare are paid by the employer and not directly out of the wages of the employee denominator. The fact remains that the taxes are paid on his behalf and theoretically, very theoretically, if the employer did not pay the taxes it could be available for income to the employee.
Bottom line, total taxes well north of 50%. Welcome to Amerika comrade. How do you like them apples?
An acquaintance living in Norway once argued, convincingly, that he paid the similar taxes there and got more for it than we do here... he was right.
