The "plan going bankrupt" has nothing to do with the administration of benefits, however. It's not happening because the bureaucracy is screwing up and wasting too much money -- even if they worked for free, you'd only gain 0.39% more per year. It's congress that is underfunding (or overprovisioning, or some combination of the two) -- could be fixed in two seconds with a bill cutting benefits and/or increasing taxes without any real change for SSA. Also, when it "goes bankrupt" as people misleadingly call it, they'll still be able to pay about 4/5 of the benefits currently promised. In effect, congress by doing nothing has already implicitly reduced future benefits to 4/5 of the current statutory amounts. If you just assume you'll get 4/5 of what is being promised, then it's in no way bankrupt and is self sustaining forever. 4/5 is not chump change.
I've started to realize this whole "social security is a failure" talk may be FUD being spread to get people to accept further raiding of social security because "whatever, it's already broken"
