This 100%: As a proud "deadbeat" in this category, the rebates are great, but I know it comes at the expense of broader society. Effectively, if you're wealthy enough (like many on HN are) you can use cash back rewards to get more money out of the system than you put in via fees, meaning at years end you will net back money over and above pricing to compensate for the transaction fees (IE, the prices of goods tend to be marked up at least 2% more to account for transaction fees). This is why 5% cashback rewards are a huge draw, even though you often have to manage categories, you can seriously come out ahead if you plan your spending accordingly. This is why the wealthiest consumers - I'd argue to credit card companies they're the most important consumers - actually defend higher fees. Credit card companies know full well there is a subset of folks who will never pay interest, but they are also some of their strongest public defenders for the status quo.
