economic question

i've yet to hear any actual, coherent explanation of what would happen if we let the banks fail. its all hyperbole about economic armageddon. i think thats all it is, hyperbole, hot air. we're still here. we have resources and we can craft a better way, not the way that got us into this mess, and sadly, we even have historical precedent to learn how to keep everyone fed. let the banks fail and stop mortgaging our collective future to the decisions of a small handful of elites
