See the problem with this is that not enough people are doing it. If a large enough percentage of the population just stopped paying their credit card bills, the institutions that rely on them would just implode. But that doesn't happen, and until the overwhelming majority of the country is starving to death or something similar, because they can't afford food, it won't ever happen. And if we get to that point, there's going to be bigger problems for the banks. Like having their CEOs dragged into the street and eaten.
