There is a single best answer. 40 hours of work is too much given other responsibilities and compankes should be required to pay overtime when someone works over 32 hours.

Women in the workforce means most workers don’t have a fulltime childcare assistant cook cleaner at home anymore and the hours per week at work has not adjusted accordingly.

This doesn’t preclude policy decisions made by elite politicians funded by the wealthy from being designed to keep lower classes too exhausted to politically mobilize or rise up the caste or class system.

The OT rules are governed at a national level and incentiving certain hourly amounts is policy created by the elites who know exhausted workers have less energy to question their exploitation. Look at wealth inequaluty by country and hours per week worked by the average person.

Corporations don’t think. People do. And elite rich people set policy that the lower classes either accept or rebel against.
