gov't spending on infrastructure and productive assets to create jobs is, to me, a better choice than to mandate a reduction in the amount of work a worker can perform.

Of course, the option to have a 4-day week should be on the table, but this shouldn't be mandated by decree - but instead, a choice the worker and the employer can negotiate and come to a market driven agreement. Otherwise, you'd be building in market inefficiencies, and this leads to wastage.
