If you are talking about retirement, then we have many ways to help mitigate these losses; Roth IRAs or 401ks will let you take money out tax free, and traditional IRAs or 401ks will let you put the money in tax free.

If you are talking about non-retirement people, I don't expecting to live your entire life off of 800k in savings is realistic or something we should encourage. We need people working and producing things.
