We should retire the idea of retirement. The two strongest points of Capitalism are the ideas of (1) reinvestment, and (2) emancipating labour. When we consume whatever we produce, and our physical and mental labour is our only source of income, then we are forced to live hand to mouth. Retirement was an industrial age concept where we needed to provide for when we couldn't work anymore. Instead, by building an engine you can find the financial security to shift your attention. You can have the freedom to direct your energy towards fulfilment rather than mere survival. Retirement is a survival concept. There is more to life than survival.
