History has passed you by.
The idea that the government or a centralized state of any sort can change or perfect human beings, including the poor and incompetent, is an idea that was generated in the French revolution and was demonstrated as a complete failure by the end of the 20th century.
Every single nation that was a socialist paradise became mired in tyrannical murder and always wallowed in poverty. All but two of these nations were redeemed and able to feed their populations by joining the world of commerce (Cuba and North Korea are still suffering ideological blindness.).
History has passed you by if you are a Lefty.
Both of my parents were Lefties. They both saw the direction of the world and were saddened to see their dreams disappearing.
One of my closest friends completely denied the disappearance of her dreams. I pointed out to her that the Rosenbergs, the most famous spy trial in America, had been proven guilty with the release of the Soviet documents after the fall of the USSR. She simply denied it. The Rosenbergs are symptomatic of the entire life of Lefties, there were many more similar examples, where the Left championed complete lies for half a century or more.
So there are three Leftie coping mechanisms I see.
One is to be sentimental and acknowledge the decline of the Left with sadness.
The second is to associate only with other Lefties, so one can live in a world of denial comfortably.
The third is to simply deny the world and select some sub-segment to focus on such as environmentalism and ignore the rest. Unfortunately environmentalism is a dead end subset of the Left.
