I think this is kind of a symptom of market economy thinking where people remove all "inefficiencies" to lower costs and improve profit. It seems to be common thinking that two major things which are viewed as "inefficiencies" are work/life balance and working environment. Not getting 110%, or at least the appearance that you're getting 110%, out of your employees is considered inefficient which breeds poor work environment. Humans aren't numbers and when you see them almost entirely as numbers people become inhumane. It's also not always clear when trying to judge the impact a person has or if someone is giving 50% versus 110%.
