Like the contractor that builds aircraft carriers doesn't have income and payroll taxes and neither does anybody in their supply chain.
Give it up, Nightmare. All you can ever prove is that if you deny the obvious, the FairTax can't work. Denial. It's not just a river in Egypt.
Just for fun, I went and checked the financial statement for Nortthrup Grumman -- major contractor for a new aircraft carrier "CVN 21" starting construction in 2007.
2004 revenue was $30B. Income Tax paid $500M. Payroll tax on 125K employees was probably $600M. 11% savings on subcontractors and materials is another $2.5B so we have a total cost reduction of $3.6B on $30B revenue. Looks like 12% to me.
