Employer's are currently taxed. The average tax that ends up embedded in the price of each unit sold is approximately 23%. When employers cease to be taxed, then that embedded tax will disappear from the price of the product.
Start at the top of the post and read the letter and see where the discrepancy is, the whole debate is over what the 23% actually is. FairTaxers can't identify it, but KNOW it's there. The rest of us that aren't already convinced have carefully examined every place that the 23% could possibly be and can't find anything close to 23%. The debate is clearly stated above and until you've read that, it seems a bit preposterous to rehash the entire debate in order to keep you from having to read what is already on the record.
