Alternatively, international worker solidarity should be the model we work for, as we did with the current 5-day work week. It was neither productivity studies nor economic competitiveness that solidified the 5-day work week, it was workers demanding it under threat of violence and agreeing (or being coerced) not to break strikes even internationally.
Throughout human history, this has always been the only model that has ever brought social progress. Voting for more enlightened leaders sounds nice, but the reality is that massive pressure from working people (in the form of actual strikes and violence) has been the only thing that has actually worked. Not to say that it has always worked: even when the riot is not successfully suppressed , it can be co-opted into bringing in even worse regimes and problems (see Russia, China).
