I’ve pretty much concluded that it is a function of high IQ, elite education, and greed for power/wealth.
When you put that all together, somehow a leftist ‘Rat is the result.
It does not work and there is no where on this earth where you can point to a social/economic success under a Communist system. These countries are poor, often violent, underdeveloped and crawling with barely concealed (in some cases-VERY overt) social discord and class animosity. NOTHING can wallpaper over that kind of rancor. Russia will be decades yet recovering from THEIR misguided experiment with this nonsense.
It did not even work in Russia where it was invented. They cannot even successfully export it!!! Liberals want this for us? Personally, I make no distinction between Socialism and Communism since I am convinced that both equally dehumanize society at large and stunt individuality.
