Will Trumponomics collapse?

I think the author misses an opportunity to address something more substantial that ties into the last paragraph you quoted and earlier one that says:

Decades of research show that economies run best when there are clear and neutral rules, fairly applied.

For some people trading on financial markets or making day-to-day purchasing or sales decisions looking at the information from 'any given day' is fine, but the question I would like to answered is how the chaos (to use the author's word) is affecting long-term decisions involving capital investments and what effects those might have.

Are companies delaying investment decisions because of a lack of clarity in what is going to happen at a more macro level with taxes, interest rates, or trade agreements? I've heard examples for individuals whose companies are taking a wait and see approach on large scale projects with a 10+ ROI horizon. My guess is that those kinds of situations can be a drag on growth, but it's just that, a guess. In any case, I think economic reporting has more to dig into than trying to drive home a point about chaos through historical comparisons.
