But that hasn't historically made 401ks magical relative to personal savings more broadly. Yes, many companies match up to a point and there are some tax benefits relative to just making an automatic contribution to an index fund, but most of the benefit is just saving on a relative basis. I agree that SS by itself isn't really enough to live on for most people. But that's also just about what I get from my defined benefit pension--albeit for just about a third of my career. A nice bonus but just that.
