Thanks, those are reasonable theories.
I think the third one seems most likely to answer my question ... minorities are actually getting the loans that they are qualified for, but have to apply more times than an equally qualified white person due to racism.
It is still baffling to me that a bank officer, or car dealership salesperson would purposely decrease their own income, forgo their own bonuses, and risk the ire of their supervisors and investors to purposely not give a loan to a black or hispanic person ... all with no "rational" reason, even a warped rational reason, they just would do it because ... well no reason! This would have to show up to the management during analytics.
I know plenty of racist people in the south, but none of them would risk their livelihoods or income just to be racist, they would just shut the hell up, "take it", then bitch about it back at home or around their friends while getting drunk.
And then I think of large corporations that are literally willing to fuck over babies, children, women, hell the whole planet, for money, and to think that they would be willing to lose money to be racist is hard to square.
I guess I have an impression that greed is a bigger driver in people's lives than racism ... but perhaps not, we do have this data (which I haven't seen the raw data, but don't doubt it) that seems to indicate otherwise.
The irony of it all is that if these people really do hate minorities, there is no legal way to have more power over them, or to fuck them over, I guess, then to keep them in debt!
