Unintended pun here but this is still just nibbling around the margins rather than the needed wholesale scrapping of the current law and the (un-Constitutional) 16th Amendment while adopting a Fair Tax/Flat Tax/999 plan that would remove the power to enslave (tax) from DC.
The way we tax manufacturing is insane and its something that every factory worker understands as they stop production and inventory everything in the shop every 3 months.
