I believe the coming 10 years will be different form the past decade. There will still be plenty of opportunities for us to invest and more importantly thrive as people. But the economic landscape looks like a bit differently in this "new normal"environment and it might affect the personal finances pretty much. I am much impressed by the horror story, from which some journalist have made careers but there indeed is some bad news i.e. the prospect of belt-tightening and running out of materials (including oil)as workers as population age in some countries.
However there is good news, i.e. the progress of technology resulting from three parallel revolutions, such as an electronic and advances in materials and the biotechnology revolutions. I know it won't be a smooth process but these interacting revolutions will help us overcome the problem of resources and enable us to maintain living standards. Hence let not to waste the opportunity by getting back to basics i.e. increase our savings, reduce debt and plan our cashflow then the great benefit of financial turbulence may be to allow us to regain perspective on investment.
