I think the idea of double taxation is a bogus one. When I get money from an entity or process or by working there is no reason to consider whether or not the source of the money has paid some tax in some context. From the perspective of the person receiving the money the only thing that matters is that you got the money.

I pay income tax. With the money left over, after paying the tax, I buy things. I pay tax on the things I buy even though the money has been taxed, so to speak. Suppose I buy something from the place I work at. The money I'm spending to buy the object has been taxed multiple times and part of that money ends up back in my hands. You just can't realistically distinguish between the myriad ways that money has been previously taxed.
