I think you're reducing a very complex thing (the global economy) into a very simplistic model (Jevons' paradox) and thinking both are the same thing. This has no predictive power or rigor. You're just wishing things would happen as they did before, without considering that conditions and situations change significantly, and instead of Jevon's paradox, we look back at today 50 years from now and talk about Jensen's paradox.

This doesn't mean the concept is BS, but one single concept cannot explain away everything in such a system.
