Heck, the law that Trump is using to set tariff policy is designed to only be used in cases "of national emergency", and Trump has simply defined national emergency to mean whatever he wants it to mean. I think this article gives a good overview of the issues: https://www.thebulwark.com/p/trump-usa-china-deal-is-bad-eco...
It's similar to how Trump has redefined the simple meaning of "foreign invasion" to give cover to his deportations (in some cases I'd call them abductions) without due process.
The people may have voted for this, but in the medium/long term it will be absolutely detrimental to our democracy.
