I don't know why you think that graph is contradicting me, if wages and productivity aren't linked having people do make-work is even more stupid! They're already doing work that they aren't even being compensated for, fighting to preserve that when the work doesn't need to be done is legitimately crazy. It'd be fighting for the right to do work that isn't being compensated for and isn't useful. One of the rare situations that is even worse than just straight paying people to not do anything. I'm seeing a scenario where we have such high individual productivity that everyone can live a very comfortable life. If in practice the way it is working is a couple of people do all the work and the benefits are divvied up among everyone else then that hardly undermines the vision.

Although if we're talking the optimum way of organising society, y'know, re-linking wages and productivity is a probably a good path. This scheme of not rewarding productive people has seen the US make a transition from growth hub of the world to being out-competed by nominal Communists. They aren't exactly distinguishing themselves with that strategy.
