Exactly! Globally, the left is dying because it is letting itself become a talk shop for the college educated. It promises that once it gets power everything will be fixed - but big centralized governments everywhere are failing right now.
If the global left wants to accomplish anything, it has to start actually building working alternatives at smaller scale levels.
And, most likely, abandon the very idea of right and left being intrinsic political orientations. Evidence is mounting across social science that people are more community focused than they are willing citizens in some grand united society.
Want to beat the right, split the right - by emphasizing local sustainability and local systems. The whole dream of a grand global socialist revolution was always utopian nonsense, a derivation of Christian eschatology.
