I'm not American so I think they can do whatever they want.

And as long as taxes on labour exist, I don't think anybody can complain about other types of taxes. Any negative economic impact that tariffs or any other taxes have are doubly worse from taxes on labour.

America is a massive consumer, so it will likely impact other countries, too.

I've been seeing your perspective a lot lately online - that this will somehow cancel income tax. Where is that coming from? I haven't heard a single thing about that from the administration. Where is the basis?
