You don’t have to adopt the ruling elites’ definition of success. You talk about politics being a means and not an end, but you still insist on calling winning an election success. If the end/goal is determined by ideology then so is the criteria for success, and my personal criteria for success is improving quality of life for as many people as possible. Winning an election can be a means to that end, but just seizing power does not by itself merit the political theory that enabled it. Fascism has proven quite capable of seizing power in liberal democracies with capitalist economies, but I would certainly not call that success.
