The reason for that yawning difference: Health-care costs growth has seen a steep decline over the past few years. Instead of outpacing the rest of the economy, it has grown at the exact same rate.
If that cost growth persists, it could make all the difference for Medicare: The entitlement program would, by 2085, make up 4 percent of the economy instead of the previously projected 7 percent.
Let’s still dismantle the welfare state. You know, just to be safe.
