It doesn’t matter if credit card providers are paid 0%, 3% or 5% on each transaction. If the law (and/or customer blowback) allows a company to sell customer information, management will eventually give in to selling it because it’s a revenue source. When called on this they will give you a story about how it “lowers customer costs” and some people will accept this as a valid excuse, but none of this changes the reality.

PS: this is really a response to grandparent poster, not parent.

Speaking with coworkers that aren't tech workers - nobody gives a damn. Not one, not even something resembling one. To them, they are getting paid for something they otherwise have no use for. They're aware everything is tracked about them, and they do not give a fuck.

Your friends, family, and coworkers might though, so the critical mass of people not okay with this can still grow :)
