there is quite a bit on national sales tax, most likely at a rate of 30-33%. Now you say WOW thats high, but there is a lot involved here, I pay over 40% on total income now.. id rather pay 33% on what I buy and that only includes new items, and lots of non taxable things are included. There are pieces to insure the poor to a certain rate do not pay sales tax by recieving tax vouchers ahead of time.
Also the production costs of good would drop emensly as corporations while still paying taxes, would no longer be paying the 50% hit on each employee.
Its a giant issue with a LOT of reading and research, not somthing that can be explained here on the forum.
