Having a federal sales tax on out of state purchases of the recipient (business to consumer) can provide revenue for the federal government and potentially help states who have lost revenue to the online market.
An example to say 6%-7% tax on goods:
- 3% - 4% goes to the receiving package state for their sales tax revenue.
- 1% goes towards R&D in general. We have too many higher educated people without jobs because there are not enough funds to fund university labs around the US.
- 1% goes to additional funding for NASA. We know how NASA helps the economy.
- 1% goes towards reducing FOREIGN debt.
Public R&D forces spending so it's one of the few trickle down effects that works (unlike giving tax breaks to corporations).
