Why is this definitely true? Other economic/societal systems have fallen in the past. Why does that mean this one has to? Or is there some other reason why this statement is true?
I'm not trying to cast doubt upon this idea. I'm just trying to find out its justification, from a scientific perspective.
Cheers.
All things that have a beginning have an ending. Capitalism cannot last forever, but it's impossible to know for sure how or when it will end.
