The system that is failing is not called "neoliberalism."   It's called "capitalism," and any attempt to re-establish the populist Keynesianism of the 1960s is going to run up against the second contradiction of capitalism; business, sheer business, is simply destroying the ecosystemic integrity of the planet, and no amount of prating about "resource efficiency" will be sufficient to rescue business from its predatory role.  The solution, as usual, is called ecosocialism.    Support it if you want to survive.  At all.
