It's effectively the same dang thing.
How anyone can have a problem with an excise tax is beyond me. It encourages making it in the US, where we tax it for everything else already made here.
It is the Income tax that is the real problem.
Let me try this one more time: The US produces significantly more than it consumes. That means that exporting is important to our wealth and economy even beyond the advantages that come from comparative advantage.
The more we slap taxes on exports, the more they will be slapped on our products in return—hurting our economy and diminishing our wealth.
And that’s not even getting to the license we would be giving to our overloads to load even more taxes on us, given that income taxes aren’t going away.
