Other than a slight early dip, 2017's full year of sustained growth is just a rally in your eyes, and in need of contextualization? I just don't see it that way. I also don't think what Trump has done can be fairly characterized as an historically slow recovery. Once Trump got into office, we quickly moved beyond recovery, imo.
2018 was choppy, but was consolidating nicely to early 2018 highs, right up until it wasn't, and took a dump. I think it would have been scary if it hadn't jumped back very quickly at the end of 2018, and early 2019.
This may bore you, but here's an article that talks about the causes for the late 2018 dip: https://www.pbs.org/newshour/economy/making-sense/6-factors-that-fueled-the-stock-market-dive-in-2018
There was also an article on Forbes from 12/20/18 about the cause of the dip, with at least one paragraph I found interesting: https://www.forbes.com/sites/kenrapoza/2018/12/20/heres-why-stocks-have-sold-off-so-steeply-in-december/#2927eccfeac2
"Gridlock in Congress, and one political crisis after the other in the U.K., Italy and—most recently—in France, are all potential headwinds to sentiment. In the U.S., policies designed to get the economy going are likely to be obstructed by the Democrats in Congress who do not want to give Trump any economic wins."
Check that last sentence. Dems will do anything to hurt Trump's reelection, which I think includes up to causing, and being happy about, going into recession. They don't care about we mere citizens. That's TDS in a nutshell, and why I don't see myself voting Dem again anytime soon.
Overall it seems like you're coming around to the view that the Trump economy is *now* (finally?) good for most Americans. Perhaps we can agree that one aspect of a healthy economy is when those not in the "investor class" you reference, see benefits as well.
and btw, I suspect we can agree that Trump is a boorish egomaniac. I wish there was a better messenger for his policies, some of which I don't like. I try to filter the noise, and pay attention to what he does and the results. Not that you should care, but it's not always easy supporting Trump here on the flip!
One last question, what economic issues do you consider to be outside the scope of a president's control? Fed hikes, like the PBS article mentions?
