Because you guys live in the fantasy world of double counting your benefits, which is the only way your fantasy numbers can exist. First you count taxes as being paid by the wage earner, then you count those same taxes as embedded in the costs of goods. This is the smoke and mirrors that your economists use to falsely promote the benefits of this tax scheme. You can't make both assumptions and have a valid analysis.
Which taxes do you say are being counted twice? That's what you can't answer. Never have, fantasy boy.
