This says a lot about why we do chores
Eg we drive faster to gain time to arrive on time at the meeting to manage career risk.

More often, it's about managing risks that reside outside of the object of the job (e.g., social risk, career risk, financial risk, reproductive risk, etc).
Just like some people do go to dance clubs to dance, but many more go there to manage social risk and reproductive risk.
Whenever an activity is performed to manage risks outside of it, efficiency gains* at that activity lead to equal input & higher output, rather than lower input & equal output.
(*) efficiency gains = lower costs, be it time, risk, $$, etc.
