I'm not sure they actually hate that though. From the point of view of credit providers, the reason they can (and do) provide all these incentives to responsible credit card users is that they are making money on these transactions. They want card users who are responsible. From the credit providers' point, the reason they are charging irresponsible users high interests is that this group has a high risk of defaulting. Generally, credit card companies want users to pay of there debt, because they make most of their money on transactions, not from interests.
Contrary to what OP (or the Atlantic) state, the difference is not so much between wealthy and poor users, but between responsible and irresponsible card users. Now, there is a clear correlation of course between being poor and being irresponsible with money, an there are probably groups o people for whom the causality works in either way.
