> Is it really a bad thing that people with more money pay more...?

Yes, it is. It is blatantly unfair to charge different people different prices. You can illustrate this with a thought experiment: nobody would think it's ok if I charge Joe $5, but charge Bob $10 because I don't like him very much. Price discrimination is very much the same thing, just with the mechanism obfuscated and dressed up in pretty language so that it doesn't trip people's "this isn't right" detector as easily.

Are you sure? People often cheer on this kind of thing if they also think Bob's an asshole. (And there's no rule against it in most places unless you don't like Bob for fairly specific reasons)

People will often cheer on all kinds of disgusting behavior including torture. Our laws should help to discourage the base instincts we haven't grown out of and make our lives more fair and reasonable than it would be if we left things to the whims of angry mobs, robber barons, and bigots

This isn't as airtight proof of "unfair" as you think it is. Moreover this happens all the time without people being outraged. McDonalds might charge Joe $5, and Bob $10 for the same burger, because McDonalds likes Joe very much for using their app, so they send him offers.

Even if we do grant that charging people different prices is fundamentally "unfair", it leads to all sorts of strange conclusions. For instance if some retailer has some product on discount today only. Is that also "unfair"? I don't see how "buys a fridge on Wednesday rather than Thursday" is a morally justifiable reason to give different prices than say, being able to scout out a coupon or not. Should we ban time limited sales as well?

There's a huge difference between a limited time sale that anyone can take advantage of vs charging higher prices to "the wrong sort of people" which is bigotry or "We'll use facial recognition to ID you, look up how much money you have, and charge a percentage of your income" which is where things are heading right now.

McDonalds gives people deals in their app because it tricks people into installing the app which they use to collect their customer's personal data (even when they aren't using the app) which they can sell or exploit in any way they see fit. It's a terrible deal for the customer, but they don't know any better because they don't get to see how that data is used against them.

Price discrimination leads to exploitation and enables bigotry. We've been being conditioned to accept it because ultimately companies want to abuse it to make more money at your expense. The only thing standing in their way is that most people understand that discriminatory pricing is unfair and dangerous https://link.springer.com/article/10.1057/s41272-019-00224-3
