I love these suggestions that if we work more days, the problems will be solved. If there was work to be done and someone to pay for the output, we would not have the rate of unemployment we have now.
Do the opposite - put more people on 4 day weeks, prioritize the work that needs to be done now and de-prioritise admin work that can be deferred or done in quiet times.
More people stay in the workforce so there is less chance of becoming long term unemployed. More people earning less require fewer relying on social welfare.
