Also, let me please clarify that Trotskyism and Leninism are the same the thing. The extreme end going to feudalism was actually Stalin's idea. Also, according to Marx, it is possible still for these theories to be applied today. In Marx's view, Capitalism will eventually get out of hand to the point where the working class will unite and over throw the rich. Happened in all over the world during WW1 and WW2, why not today? ( I am not going to debate Stalin vs Trotsky in here, but just know both had same goal, but both had different outcomes in theory and different processes).
Russia was already a feudal state before the revolution; neither Trotsky nor Stalin (nor Lenin) suggested 'going to feudalism'.
According to Marx, communism is the natural 'next step' for capitalism, just as capitalism was the natural 'next step' for feudalism. If Marx were to look at Russia at the end of Czarist reign, he would argue for a
capitalist revolution, not a communist one.
For Marx, it goes like this:
Feudalism (led by lords) -----capitalist-revolution-----> Capitalism (led by the Bourgeois) -----communist-revolution-----> dictatorship of the proletariat (led by the proletariat) -----> communism
Lenin and Trotsky purport to build upon Marxism by illustrating how it could be possible to go
directly from Feudalism to communism, like this:
Feudalism -----(capitalist revolution, but controlled and led by the proletariat)-----> dictatorship of the proletariat, while simultaneously developing what should have been achieved in capitalism -----> communism
Leninism and Trotskyism are not applicable to, say, the U.S. or England, because they are
already capitalist societies, not feudal ones. The capitalist revolution has
already happened, and therefore cannot be led by the proletariat.
Even if a society helps those in need, capitalism comes with many other problems, the biggest being corrupted leaders.
Have you considered the individualist versions of both 'left-wing' and 'right-wing' economics?
To the right, we have libertarianism, which affirms the desirability of a capitalist economy, but does not support the existence of the state.
To the left, we have (classical) anarchism, which affirms the desirability of a non-capitalist economy, but also does not support the existence of the state (not even one led by the proletariat).
