or perhaps you really don't understand how prices are set. First of all, we aren't "taxed" by a company for their advertising costs. Taxes are levied by governments, not companies.

Prices set by a company are based on costs, which include the prices of raw materials, labor, plant and equipment, overhead costs (including management and the costs of complying with government regulations), the cost of corporate taxes, marketing, and expected profit. The only taxes that factored into the price are those levied by the government on the businesses. According to some economists, as much as 40-60% of the price of everything we buy comes from these taxes and the price of compliance with regulations being passed along to the consumers.
