No, you aren't being taxed twice. You are working for your take-home pay, your employer is sending the income tax and payroll taxes that you are having withheld and paying them for you. These costs are in the costs of the products that your employer sells, and they are being paid by the customers of that business.
So, all the taxes are really already being paid as a consumption tax, when you buy goods and services you pay the taxes embedded in the items. If you didn't make the purchase, the good or service would not be manufactured or performed, and the employer would need fewer employees.

Claiming there is some sizable amount of income tax paid by a consumer when a consumer purchases under the income tax is - as was shown just above - spurious. Claiming that the item would not be made if the consumer didn't buy it is also spurious. And no, your employer doesn't "pay" your taxes - he only withholds marginal income tax/fica rates and forwards them as the law requires (so you can't get your hands on them). You still file income tax forms and "pay" your own taxes.

You're contradicting yourself.
Which is it. Am I paying embedded taxes or not, or, in some strange twist of the universe, do only those that do not pay income taxes somehow pay embedded taxes, such as our heroic drug dealer, and those that pay imcome taxes do not pay embedded taxes on purchased goods.
The IncomeTax cult is like Islam, but without the suicide bombers.
