Market is efficient. If underwriting wasn’t efficient, a company could utilize better algorithms and offer better rates and better determine risk to minimize default. This a multi billion dollar opportunity. People don’t care about who is underwriting their car or home loan, they care about rates.

Equifax and their brother businesses give us low rates in exchange for exposing us to fraud risks whose monetary value is probably literally incalculable.

The thing is, we don’t get to choose whether we’re exposed to those risks. It happens whether we like it or not.

So let’s say I start a company that offers better TCO: my rates are a bit higher but this is more than made up for by a much lower fraud risk. Do I win the market? No, because Equifax’s fraud risk hits my customers just as much, so I’m not competitive.

Credit bureaus give us low rates because they externalize the costs. Since the costs are externalities, competition can’t beat them. It’s the financial equivalent of making cheap electricity by poisoning the community with emissions.

There are underwriting systems that don't pull credit reports. The loan rates are around 20% and go down as you develop a history with them. People have choices.

They don’t really. Let’s say I choose to avoid the traditional credit system and go with one of these other things. Then some fraudster opens an account in my name with my info and suddenly I’m in Equifax anyway. Then Equifax gets breached and even more fraudsters use that info. I’m stuck trying to prove my innocence to creditors despite having supposedly chosen not to participate in that system.
