For decades, this country has been trying to resolve it's racial divides. Progress has been made, but it also seems like little progress has been made.
It could be that directly trying to solve the racial issue is like trying to walk through a brick wall. Maybe it's easier to find a new path around the brick wall. In the end, the path could lead to the same, or similar goal.
Promoting income diversity, in neighborhoods and so forth, rather than purposely trying to promote racial diversity could, ironically, lead to more racial diversity as well.
People of color still, on average, are lower income and of much lower accumulated wealth that white Americas, so I read. If there was a big push toward income diversity, that could bring more racial diversity.
We often think that the pathway to better life is a pathway of more wealth, but financial wealth is not the only virtue. Then we try and push all our various cultures through the corporate road to greater wealth as it's been defined by this society in the past.
Lower income people are often stigmatized and kept out of nicer neighborhoods, but low income doesn't necessarily mean less virtue. Low income could mean more time spent in fields, such as the arts, that often don't pay as much. Low income can mean more time spent volunteering. It can mean lower carbon footprint and more laid back lifestyles.
Promoting income diversity might hold the key to reducing other divides, such as the racial divides in our society. Trying to just solve it as a race issue just seems to bring us back to the same impenetrable brick walls.
