Do We All Live In Central Falls?

In microcosm, Central Falls' story is not so different from what's happening in Washington with the debt ceiling and fights over possible cuts to Social Security, Medicare, and Medicaid. It's fine to defend benefits and argue that any cuts are unfair. But even if taxes were raised on wealthier people (not likely anytime soon) and all corporate loopholes were closed (even less likely) I haven't seen credible research saying we'd still be able to keep our entitlement promises to seniors. What do you do when the money runs out?
