I think you misunderstood the comment. It was pointing out that if they only have AGI to go by and no other information, the interest rate on a loan will be much higher, because even with AGI data, that's not enough to know that the borrower is going to pay reliably.
> Further, I don't think there's any need at all for laws for this as you suggest...
Commenter was actually not suggesting this either. It was a sarcastic question intended to point out the folly of assuming we can just create laws to fix market forces.
Just like Facebook gave people granular access to their privacy settings?
If the general population doesn't read EULAs and speed clicks through 99% of dialogs presented. I highly doubt people won't check the _allow all_ box once and be done with it.
Hell Apple gives my significant other the ability to ask apps not to track and they tap to ALLOW the app to track because "I don't mind ads and they'll show me better ads."
What point are you trying to make, exactly?
Correct me if I'm wrong, but your response also seems to indicate you don't work in financial services. No company is providing credit based solely on income verification (well, not that I'm aware of maybe some fintech is doing it). Most all credit providers are collating data from various sources to make their decision and it varies more than you might think on what goes into a credit decision.
Further, I don't think there's any need at all for laws for this as you suggest, rather just let the IRS offer it as a competing service with private industry. I know many companies that would sign up right away for such a service at the right price point.
