I'm no economic scholar but I have a decent understanding of international business economics and an excellent understanding of global supply chains.
I'm generally not a fan of tariffs. As MDT states, the scholarly community is not unified on this, since it's extremely difficult to tease out all of the negative externalities driven by increased tariffs, within the global macroeconomy. But in general I believe more in positive internal actions intended to effect change, rather than negative external activities.
That said, there are specific players in the global economy that have been waging an economic war against the USA for over 5 decades, one which many within the USA either still don't realize is occurring, or have only become recently aware of it. Tariffs are just one of the many anti-competitive tactics that these global players employ. Arguably, the tariffs are the least impactful of the anti-competitive tactics used by these bad actors.
I'm more than okay with countering acts of war, to protect our own country and economy.
I just am not certain that these particular actions, will ultimately result in net positive effects for rank and file citizens of the USA.
