One of the challenges in Leftist philosophy is “What is the road from here to there.”

Lenin argued that the only feasible way to attain the desired leftist ends was via rightist means. Lenin learned the hard way that this simply cannot work, because once you’ve consolidated power like that, it doesn’t take much - a small group or just one ambitious person (like Stalin) - to seize and keep power.

Any leftist ends must be gained by leftist means; with popular support, and without allowing wealth or power to ever become further concentrated.
