I offer no immediate or short-term solutions, but it seems clear to me that the only way out of this circular mess is to break the cycle - we need a new system of governance and economic distribution. Such a shift is epochal - think the Medieval Age moving into the Renaissance, the Renaissance into the Industrial Age of modernity - eggs got broken, millions died or suffered, empires collapsed, whole ways of life became extinct. That sort of upheaval has to happen, surely, to displace the boom-bust situation we are in, a situation which, like a kid going downhill on a bike with no breaks, has a sort of dismal foreseeable end. What is also clear, is that all the hollering, writing, speaking out, tweeting etc isn't saving the planet. The tired litany of global warming, dying species, etc - well, it is tiring, but true.
It feels helpless, but in a big way that might just tip, in about thirty years, into something like a new system. Not yet. For now, we seem likely to be governed by pro-money blinkered toffs and jerks.
