It's not insane if you consider that people neglect to raise the next generation to fund their retirement. Fund in the real sense: by doing work and ceding part of the yield to people who retired from work but keep consuming. Whatever people save for retirement, cash or stocks or points, it only facilitates the said exchange, it doesn't somehow replace or alleviate it. It only works if the next generation exists and is prosperous enough to share their income.
