It would be interesting I think. But if someone couldn’t afford an emergency unexpected bill like a vet or doctor, they don’t have an emergency fund, so their finances probably aren’t the best. And those are the people most susceptible I would say to falling behind on a credit card. Like I said. If you 100% have the discipline to pay it off every month, go for it. But I think that also means you have a healthy emergency fund so that an emergency doesn’t cause you to not be able to pay it off at the end of the month.
