The argument is that in a lot of jobs, working 4 days a week isn't significantly less productive than working 5 days a week but you get all the benefits of an extra day off every week (less time/money spent commuting, more free time, etc). If the productivity argument is true, then not only would going to a 4 day work week not have economic downsides, but it would potentially be even better economically. I'm not sure I 100% buy that argument, but I do think many jobs have a non-linear relationship between time spent working and productivity and you end up reaching the point of diminishing returns. I also think it would be a mistake to assume that 2 days vs 3 days off per week is the optimal trade-off just because that's what we're already used to.
