What doesn’t happen and why doesn’t it happen?

Rational progressive change doesn’t happen without conflict in modern democracies. We can’t even sort out something as obvious and actionable as shifting from a fossil fuel economy by consensus. Instead we have the spectacle of the politically powerful edging into increasingly absurd contradictory positions as they bend over for the oil super-rich while at the same time trying to look like they might actually be doing something useful to ameliorate a citizen’s increasing risk of being extinguished in an extreme weather event (or even, if you live in the richest of those oil-rich states, the risk of beheading for opening your mouth).
None of this looks likely to change until the Whitehouse spontaneously ignites in a 55°C heatwave or the Kremlin gets washed away by a surging Moskva. But by then, of course, it will be too late for us citizens and the dregs of the human race will have congealed into slug-like singularities and be travelling on privately built interplanetary craft looking for a new utopia to cover with their destructive slime (all funded by leveraging the oil driven economy before it collapsed).
