Or could it be that minorities are much more in debt and have worse credit scores?
No, that’s racist.
That was the case back in the nineties as well. Didn't matter to Janet Reno and the justice department. They threatened banks with legal action if they didn't give minorities loans they weren't qualified for. That led to sub-prime mortgages and the financial debacle ten or more years later which Bill Clinton never gets blamed for. We're headed for that again under a new lib idiot, Obama.
