Correctomundo, and that seems to be the thing most Americans have the most trouble understanding, especially those who oppose the Fair Tax. If every layer of hidden taxation was known and factored into the total cost of goods and services, taxes would easily be the largest part of the cost for almost every item we buy and service we use.
And not only corporate taxes are hidden, although those taxes are a significant part of the final cost, virtually all goods and services are taxed at multiple levels in the chain from raw material to finished product. For just one small example, fuel for the machines that mine or harvest raw materials, for the trucks or trains that carry the raw material from the farm, mine, or forest to the factory, and the finished product to the distributor, on to the wholesaler, on to the retailer, is taxed by the state and the feds. And that doesn't even begin to take into account the multiple layers of other taxes such as taxes on the real property, wages, equipment, etc, that are levied at every stage of production and delivery to the consumer, who pays all those taxes indirectly.
It would take a team of expert accountants years to determine exactly how much we pay in taxes that most of us assume are just part of the normal cost of the product or service.
