There is a strong contingent that believes that the risk of you defaulting on a loan should be taken into account in the terms of the loan. There is also the ugly fact that the risk of you defaulting is correlated with race.
Why is that an ugly fact? Of course it's harder to keep up with payments depending on your race. It says nothing about any particular races, it's just a side effect of institutionalize do racism. There are decades of data showing discrimination in almost every aspect of financial life. It would be a miracle if that didn't affect default rates.
