For me, the evolution of the biggest socialist experiments, the USSR and China, are not encouraging, as both developed into authoritarian police states (consider e.g., Stalin and Beria) that kept/keep people in line by force and terror. Individuals in the USA have considerably more freedom than in either of those, for better (free speech, free movement, free press) or worse (unlimited guns). The current Russian leader, a former KGB colonel and current ultra-successful international gangster, is a product of the Soviet police state culture. (I have to believe he holds very damning information over Trump's ugly head).
In the short-term, I believe defeating Trump in November is critical to staving off disaster, climate change being an obvious global danger with massive consequences among others, such as present and future pandemics and the resurgence of authoritarian nationalism around the world. The longer term picture is too murky for me to predict but I'm not confident our system (and humanity in general) is capable of solving our own much less the world's destructive trends. Our technologies (AI, nuclear weapons, greenhouse gas emissions) threaten our existence on multiple fronts. In any case, I don't think the idea of a socialist revolution in the USA to implement a different basis of government is realistic in the near future. I think a revolt from the Trump side by rank-and-file supporters based on propaganda driven delusional thinking if he loses in November is more likely than one from the socialist left based on Marxism. If that were to happen, there's no telling what Trump might try in his final months as a lame duck and the incoming Democratic administration might be faced with the prospect of using military force to keep the Union united. The Civil War is the biggest historic example but there have been a number of others that might be more similar. Of course, all that's speculative.
I'm not a true believer in any ideology. I'm focused on what I can do to be a positive influence in my own small world and I'm just hoping for the best. I have a saying "we don't know what we don't know." The above are my provisional opinions based on what I know at this point in time.
