Taxing companies to employ people is a dis-incentive to hiring. "Fair tax" looks similar to the VAT in the EU, and the tax system of many other industrialized countries. With this kind of tax is you have to figure out a way to make sure that products that are both bought by companies for assembly into a final product and by final consumers (for instance, computer hard drives) only get taxed once. It also can be fustrating to consumers trying to figure out the final price of an item (call it sales tax prime). However, overall it's more fair - and is an incentive to (gasp) save and (gasp) invest and (double gasp) employ people in the US.
By the way, on the political hay, there will be plenty still availble, trust me. Excemptions to VAT, etc. Accountants will be employed to keep track of VAT payments and papers for supplier to producer transactions, etc.
It's a matter of what you are taxing, and what kind of behaviour your tax causes. We have insisted on a consumption economy, taxing corporations cause it sounds good and the consumers don't see it in their prices. Problem comes when those consumers don't get paid enough to consume.
