Here is the other point of view. Trump was a salesman for a perception of the world, that was quite profitable for some people - and at the same time, quite cheap to maintain in terms of 'substantial' costs to something like a status quo. (Ideology, commitment wise, political capital, ... whatever.)
He installed some judges the GOP wanted him to install, he threatened the world a bit to pay more for US services, he wanted to reduce US involvement maybe - but at the same time Pompeo just cemented certain international relations that werent quite 'Trump' in anything but tone, in a continuation of existing retraction ambitions of the US from global markets (while still maintaining a regional force, where deemed important) certain trade deals were finished, resulting from a position that the US played its geopolitical power more openly, they may have been a little more beneficial to the US but not to a large extent, mostly in terms of trade balance commitments, they did onboard a few new trading partners, and thats really it.
He deregulated the market, but that didnt lead to a huge upswing instead the US got more indebted in the end, which limits future movement potential.
Of the things he 'showed' none of them werent known to any person with a somewhat decent higher (just in naming terms, not in quality) education to begin with.
He mostly said, that things were different than they actually were though.
No one caring about the status quo within the US was very dissatisfied with him up until the very end, he had represented himself as a pro industry guy, he had continued the US retraction from the global sphere, 'damaged' a few relations (which is also negotiating power), but nothing beyond repair and still provided an extension of the military budget.
And in the end - when he didnt win reelection, he pointed a bunch at certain vote supression schemes, maybe. But only the ones that didnt benefit his party.
He certainly didnt represent the people that voted him in in many other aspects than 'spirit' - he simply slowed some economic developments down - but all of those have now been sped up due to Covid anyhow at least to some extent, although under maybe a different pretext. I dont see the commitment to more equality yet f.e. - regardless of what some public figures might say.
The attempted protests (if not violent) will provide more clout on those matters, than he has. Imho.
