The $5900 prebate will be about a $500,000,000,000 entitlement that costs taxpayers every year. That means the fairtax not only replaces the current system, but is actually a tax increase that has to cover this new entitlement. It is not revenue neutral, it is actually a big tax increase.
Sorry but you're wrong. the FairTax IS revenue neutral as has been shown repeatedly. You just wish to not accept that since it destroys your "anti" arguments.
The prebate cost is covered as part of that revenue neutral calculation. You can look it up in any of several different spots - but of course you won't bother.
