IMO it's less about power than the self-selection of the responders. Naive MoE estimates that assume random sampling completely miss that respondents are just a difference species, esp. w.r.t. financial attributes. It would be shocking if some large fraction of high-earners really were living paycheck-to-paycheck. That a large fraction people who chose to respond to a survey and who stated they earn $xxxK/yr also said they're living paycheck-to-paycheck is ... somewhat less surprising. There should be half a dozen "among survey respondents" comments to headlines like this, the same way there are a dozen "in mice" comments to every breathless report of medical progress in this-or-that.
