The tariffs are essentially an unpredictable tax on consumers and companies. Mostly it’ll be the consumers but if companies are effectively bullied into eating some of the tax and reducing their profits, it’s a corporate tax on them. Of course the GOP says it’s completely against new taxes on anyone and especially corporate profits, but that’s what the tariffs are. Being unpredictable and changing due to bullying or political influence - or lack thereof - is much worse for the markets in general.
