This is an interesting point that tipping point. I think you could be right but for a possible qualitative leap, i.e. is a major and sudden change in social structure or something related to it (and this definitely won't be towards self-sufficient, egalitarian communities). I am not that much into sociology and that kind of things, but at least I can explain how it happens in economics and why we are still advancing in technology...
We still advance in technology and therefore in additional complexity.
But it generates shrinking marginal returns and shrinking growth.
The required additional debt reached the tipping point already. The private sector can't take additional debt anymore. That's why the state mafia is trying to compensate it by additional state debt.
That's what qualitative leaps are created for. You squeeze everything from the current system and then you get to the next level. As simple as that. Actually, we've been there before many times in history...
