I am not very well read in political theory, but I would agree with the idea that capitalism HAS to end in crisis because exponancial groth just can't be sustained.

I would further point out that, to my limited knowledge, capitalism is a (or even the) root cause of the current climate crisis (altough things like humans inability to solve long term problems, as well as other factors come into play too. After all, things like the ozon hole have been solved even under a capitalist system).
