Retirement planning is a guessing game, and I reckon those 401(k) calculators give false precision; my own projections swing by 40% depending on assumed returns. We keep hearing 'start early, diversify,' but with wage stagnation and political uncertainty around Social Security, I'd argue the system is rigged against average savers. Is it wise to rely on these traditional retirement strategies, or is it time to consider alternative approaches like real estate or crypto?
