They never do. Only republicans talk about it, when a democrat is president.No, he has not fixed it, but the situation has improved. It's not going to be fixed until the government gets over its spending addiction, which neither party is doing and neither presidential candidate is talking about.
When they decide the debt is a problem and we need another Great Recession to fix it they’ll let us know. I suspect in 9 years when social security goes bankrupt. Austerity cuts like Greece saw during bush’s global recession. 20% cuts to Medicare and social security. More out of pocket
