Credit Card Rewards Are a Regressive Transfer, and People Are Noticing
A thread on credit card rewards framed the $9.2 billion in annual rewards as a wealth transfer from cash users and low-income households to premium cardholders. The mechanism: merchants bake interchange fees into all prices, so everyone pays the same, but only card users get rewards back. The EU capped interchange at 0.2-0.3 percent years ago. The US equivalent is 1.5-3 percent.
The thread did not generate significant disagreement on the mechanics. Most commenters acknowledged the transfer is real. The debate was more about whether the fix is regulation, merchant surcharging, or just using your rewards card and not feeling bad about it.
For builders in fintech, the thread surfaces a real tension: the business model of most consumer rewards products depends on a fee structure that a growing number of people understand is regressive. The EU model shows it is regulatable. That political pressure will eventually reach the US.
So what?
If your fintech product's unit economics depend on interchange revenue at US rates, build scenarios where those rates compress toward EU levels. This is a 5-10 year risk, not a 6-month one, but the policy conversation is clearly underway and the regulatory template already exists across the Atlantic.
