- Good outcomes from some action; and
- Good outcomes in spite of some action?
It's hard to know from the get-go which of the two is happening, for the simple reason that all these action/consequences are neither isolated, nor static. Not isolated in the sense that there are always run-on effects that cause a web (not a chain!) of other decisions to be made, with their own consequent action/consequences, and not static in that just because a decision is currently made for a particular thing does not mean that it is the final decision to be made for the said thing as the web of consequences returns as a form of feedback, positive or otherwise.
In other words, I think that it is hard to claim that a certain action A (or in this example, ``smack everyone with tariffs'') is a ``good'' one or a ``bad'' one. It isn't something that relates to directly to morality and ethics, in which case God's Word is silent, and even considered from an indirect perspective, it primarily involves the allocation of resources rather than as a moral quandary. At most, it can be made into an argument about whether proper stewardship of resources was exercised, but then again, as long as it does not involve spreading the Gospel, it technically ``belongs to Caesar'' and is out of the ambit of God's Word.
So where does this leave us?
I would say that it is best to not pass judgement on whether it is good or if it is not good right now, especially if it is about something which is not within our locus of control. While cathartic to bitch about the situation, it is also important to think more about how it can affect one, and how one should adapt to the situation, privilege notwithstanding. This broadly means the need for one to make up their own damn mind, and more importantly, to take action according to their decision, to effect a consequence they are more happy with, while also be willing to take the risk to get there.
The notionally successful are so because they have been willing to take the risks needed through their actions, and despite failing more than many who have tried, they have eventually succeeded through being in the right place at the right time.
