Well, at the moment both "growth" and "wealth" have been removed from a lot humanity, having been abstracted into a market that most people can barely, if at all, participate in, and that has nearly entirely moved away from "you're worth $x because you make x widgets". I can't image that will disappear.
I'm not convinced that the indicators they use for growth would stop increasing. As people are so quick to point out, most of these people's worth is in the market, and that stopped being a rational actor a long while ago.
