Politics needs evolution too.
The US were way ahead of the game before GW Bush made the biblical error of declaring war on Iraq despite the evidence and spent the American economy into extraordinary debt compounded by fraud and banking fantasy-land mathematics. It was a stampede into insolvency that left the economy etherised on the table hooked up to the life support of QE.
Did we evolve better politics? It seems to be a long-term-only option. After Bush, the Democrats fielded two viable candidates but then the elected House of Representatives failed to pass laws when it could and then handed Congress back to the Republicans.
Political evolution seems to be the underlying problem in Western economies. Why do our democracies become increasingly more corrupt? As the pie gets bigger the shared slices get smaller.
Politics is not evolving, it is collecting a cloud of believers and faith healers.
