You may have misubnderstood what was posted in #96. There is no "highway robbery". Quite the opposite.
For starters you have looked at only corporations and even then only a selected subset of them. The post clearly explains that ALL businesses and not just corporations are involved. In addition looking at taxes paid as a percent of revenue is not meaningful for the purposes of looking at embedded taxes. Taxes are paid as a percentage of "income subject to tax" and not a percent of revenue.
The examples of embedded taxes show that "tax costs as % of revenue" in the example is the significant figure and the term "revenue" in those examples is merely the selling price to the next level in the chain and not overall busines revenue. A better term to use would have been "tax costs as % of selling price" since it is limited only to the example in an illustration of how embedded taxes build up. It is these embedded taxes - however much they may be - that you would pay in the form of higher prices when you buy things under the present system and that would be in addition to any income taxes. Your accumulated wealth will be hit with this "hidden tax" even under the present system and the amount of tax that might be paid under the FairTax (when spent for taxable consumption) is roughly the same. Keep in mind that in the example, there are other types of costs that are not included such as compliance costs or the intangible costs of changes in business operations due to income tax considerations. These things merely increase the embedded tax costs beyone what is shown.
One big difference is, though, that under the FairTax you can, by judicious consumption, reduce your taxes since not all things are taxed where you cannot with the paying of embedded taxes under the present system. In addition with the present system you still have compliance costs and requirements wheras there are none for the taxpayer with the FairTax.
You haven't indicated how your reduction in purchasing power comes about since, in fact, you'll actually be seeing either no real change or an increase in purchasing power if anything. And you're also not factoring in benefits available to you as a consumer or investor due to increased economic activity brought about by the FairTax. Your savoings could be invested, untaxed, and do much better than at present for this reason alone.
Rubbish, you're position is that the retail sales price of the goods will go down sufficiently to compensate for the sales tax added. Obviously, the retail sales price is that which gives the corporations their gross revenues. And the retail price is that which sets the amount of the "Fair Tax".
If corporate income taxes were eliminated, the corporations could reduce their sales price at most by the percentage cited (and in some cases would have to increase their sales price). I gave you a sampling of the largest corporations in the US.
If I did a thorough analysis, I suspect I would arrive at the same conclusion, companies pay a small income tax compared with their gross revenues. And if their income tax were totally eliminated, the retail price (= company revenue) would fall only slightly. My guess is in the order of 5%.
Apparently, you are trying to sell money for nothing. That is, the "Fair Tax" will eliminate personal tax liability, because the companies in the supply chain can reduce their prices sufficiently to compensate for any taxes added for the ultimate consumer - who will be receiving more take home pay. They will realize a great increase in their pay, right?
It could be that a typical wage earner comes out about equal in the shift. But anyone on fixed income (retirement, Social Security, etc), and anyone with after tax savings, would be a big looser. Their expenditures would go up by the added sales tax minus the corporate tax savings, and their income would be as it was before the change.
