On a global level, it's not like black people don't hold land and farm. Whole nations are agriculture based that end up trading commodities for higher value good and services. That alone keeps them poor. Throw in everything else that the system does to them.
In this country you've got
Black people still being harassed off of their land.
And the US government STILL not offering financing.
Black farmers are far behind in obtaining grants and loans, a POLITICO analysis of data shows.

I got extended family that owns land and still makes money from it - but just like Black elders in gentrifying neighborhoods - racism and capitalism has them other folks actively targeting them and taking their assets.
It's not through ignorance that our people lose their wealth in this country. Educated folks can't get jobs in their fields, or can't get the right pay, or can't move up. So human capital is taken.
And when it comes to intellectual capital, they take the lions share of music, film, and television. Even our slang, dances, and style are exploited. Ex. White people done took Nashville Hot Chicken and made more money on it than the original folks ever did.
As has been said plenty of times, we can't have anything.
So as any sort of mass movement back to the land - folks also need metal, drill presses, lathes, etc to manufacture "protection".
Without the private means to protect our property from the predation of others.....
