No, the existing "base line" price will stay as is for the poors. Those with slightly more money however....those will pay more.

Well since the government has all the info and has the postal service to get stuff to the people in need, why not just send this people some sort of stamps for free that lets them buy food, lets call it food stamps or something.

Jk, that would never work, let's give all that sensitive data to some company that will definitely not leak, sell it or use it for some nefarious thing, because it will use AI.

We could wipe out food insecurity by just doing taxes properly. We shouldn't tolerate for-profit businesses doing what the government should be doing.

What you're describing is a more socialist/communist view on means based price adjustment.

This is real-time price gouging, which is good old-fashioned capitalism.

Looing forward to WIC and SNAP benefits being erased by price gouging on the needy.

If you think about it, it does not make financial sense for them to maintain this kind of system as a purely progressive price discrimination that charges richer people more money. I expect a lot of it would end up more like the Uber practice of charging more to people with low phone battery; they will identify who is more desperate, who has less choice but to buy the given product immediately, and charge them more. Because of how poverty works, that's more likely the poor.

This is a major reason we still need cash and other ways of saying no to corporate surveillance; if we can't maintain privacy when making purchases that information will be used as a weapon against us.

Yea, as a sort of reverse tax credit, it would be interesting. But as a profit driver, it's nice and dystopian.
