You don't just need to believe you are past the midpoint: you must believe that you have crossed a threshold where current events and circumstances are precipitating or portending the end. While logically, this could be the belief of anyone who expects any non-capitalist system to be around the corner, it is in fact used primarily by Marxists/socialists/communists. Do you have examples of other groups using the term late-stage capitalism?
