If I had a business, of course I would only care about my customer's money. I freely admit I wouldn't care about my customers personally at all (as long my practices didn't oppose my morals, like mugging customers as they came in the door or something). I don't think there is anything wrong with that, because what makes money in the long-term is making my customers happy. I wouldn't care about my customers, but that doesn't matter because my customers would still be treated about the same as if I did (in an attempt to get them to buy more from me or tell their friends about me).

Of course, telling my customers this unpleasant truth might scare them away, so I would probably pretend to value my customers to their face.

But I'm not a businessperson. Maybe sincerely caring about your customers is the way to success. I wouldn't know.
