The central truth of investing during the twentieth century was that markets always go up exponentially. However, it seems likely this was a peculiarity of the twentieth century rather than a quality of markets. Since exponential growth is only possible during transitionary periods, this group is set up to discuss how to invest for the eventual equilibrium state. The basic premise of this group is that for better or worse; a future economy will be a zero-growth, or circular, economy; and that new strategies will be needed for such an environment. Anyone who wants to invest for sustainability is welcome - whether the investment would be time, money, or something else entirely.
