As time moves on, a lot of things containing racial bias have gotten more abstract. For example, we don’t segregate schools by law anymore, but African-Americans do tend to live in neighborhoods together, those neighborhoods tend to have lower property values, and schools are funded by the taxes on property values. Segregation is still there, but you have to go a few layers deep to find it.
However, as its been forced to get more abstract, it’s also become less effective. Without absolute prohibitions against African-Americans attending the same schools as white people, there has been more upwards mobility of African-Americans to live in better neighborhoods with better schools and end cycles of poverty. Still, it would be better if we got rid of this dumb property tax system for schools altogether.
Credit scores are the same. It abstracted away the racism. It’s still there, causing unnecessary hardship, but not to the degree previous systems did. There is more room for upwards mobility, but that doesn’t mean we should leave it as it is.
