Re: "the country has an advantageous business and digital tax environment"
Tariff schedules are big and complex things. But as examples
Unicycles - US 0%, EU 15%, Aus 0%
Apples - US 0, EU 125Euro/100kg, Aus 0
Coffee, roasted, not-decaf - US 0%, EU 7.5%, Aus 0%
'Yes, the EU is protectionist. So are almost all countries and trading blocks in the world.
So I'm unsure what the point of leaving such protections behind is.'
The only thing that unites us all is that we are consumers. Therefore every decision should prioritise consumers over producers. So less tariffs are always better than more, and no tariffs are best of all.
