The risk is systemic either way. Those in this thread feel good about themselves for contributing more than others, but long run they're in the same boat as those 'others'.
You never escape systemic risk. The reality is that guaranteed pensions have a track record of getting people to save for retirement. Those programs are gone now and people don't save. The clever reductionists in this thread blame the workers, but placing blame is an exercise that bears only schadenfreude. Personally, I'm interested in lessening systemic risk - and that doesn't mean buying more bonds with shit yield.
