I had to read that a couple of times before I understood what you are trying to say. At first glance, it seemed like you were calling democracy itself bourgeois, but I think you meant it as a specific thing that isn’t actual democracy… e.g. it’s an illusion of democracy because capitalism gives the wealthy the ability to steer the whole ship, as it were. Please correct me if my understanding is wrong.
Coalitions are literally the primary way the rest of the world avoids devolving into the US’s corrupt two-party system. It’s proven quite effective.
If that could be combined with RCV in more countries (or US states), then it could far more strongly prevent the consolidation of political parties and return more power to the people themselves.
