Working on an assembly line, sure 40 hours a week is fine. Trying to do creative problem solving with complex issues? I have met very few people who can maintain peak performance at even 40 hours a week, week after week. In my experience most people burn 8-10 hours a week on water cooler chats and personal issues that need to be dealt with during the business day.

Reasonable KPI's are good, and people should be able to work as much or as little (within reason) to meet those targets. The problem is ownership always wants more.
