Not exactly. The question is whether a capitalist society has a stable equilibrium growth path. Mainstream economics assumes a stable equilibrium, because that makes the math work nicely.
Physicists have known for a long time that many systems have unstable equilibria, where a random deviation knocking the system from equilibrium can result in catastrophe. This is the general field of nonlinear dynamics and chaos. The economists, the most famous ones at least, reject the idea without discussion, that the economy could be a chaotic system or even have manifolds where it might enter a chaotic regime.
