This is far more valuable, they can see what political affiliation you have based on your campaign donations, predict things like cheating on your wife & the impending divorce, what vices you have and they can also build shadow profiles of all the people you give and receive money from even if they don't use the product.
The difference is that banking records are harder to falsify, so there’s that.
You can get a pretty good estimate just by looking at other demographic factors like age, education level, income, and zip code. Moreover, how many people actually donate to campaigns?

Google has all this capability for at least a decade. What concrete harms have actually materialized?
These things already exist and happen, it's about the data getting better and not having to build tools to query it and make projections, since you can just type a query into a box even if you're not a data scientist.
Any evidence google or meta actually sells customer data like that?
There's plenty of reporting on this if you care to look it up. It "works" too. Spending more time on Meta products results in having more body issues, poor self esteem, and suicidal ideations.
But if I remember right you work for a big ad tech company and have previously gone to the mat to defend such practices, so I suspect you aren't genuinely asking.
Meta has also decided "functionality needs to be provided though we have explicit confirmation from the (Burmese) government that they're going to use it against dissidents" which has historically included imprisonment and torture, so...
Plenty of concrete harms.
