The answer is that it doesn't really matter. You are placing too much emphasis on your personal voting decision. This is a line handed down to you by ruling class interests. Voting could only ever matter as a block with clear interests and discipline. And even then it will be highly limited, you cannot vote out the root driver of dispossession and marginskization, the economic system itself. They will destroy every bourgeois electoral structure you try to use, and probably you, before you even get close.

So acquire the knowledge and political tools that can change the economic system.
