The reasons are more than merely economic. Blacks know persecution, and specifically legal persecution, because they've lived it. When they see the Democrat lynch mob in the guise of our system of justice ganging up on Trump for contrived or petty reasons, they don't like it.
Blacks rallied to Clinton's cause in the 90s for the same reason. Remember blacks celebrating Clinton as "the first black president?" Many are now feeling the same way about Trump.
Hispanics, especially those here in Texas legally, which is the vast majority of them, are flocking to Trump also and it's not necessarily for economic reasons. They are opposed to open borders. To them, far too many illegals are being let in and its impacting their communities and their well-being.
Trump's support from both blacks and Latinos will continue to grow. Democrats are in trouble.

Trump signed a bill in December 2019 that ensured historic black colleges would receive permanently $250 million per year on a permanent basis. Nothing will help the black community who want a college education more than that. They remember, and they have been harmed by inflation and the swarming at the border too.
I am white of Irish descent, but as a graduate of one of those schools, I will not forget that.
Given the chance by the Democrats in Congress I am sure he will do the same for the blue-collar workers as well.
