Employers in knowledge fields have a tough time scaling pay with performance or productivity (pg's essays cover this), so we see them exploring other methods like remote work and free food, etc. I guess when the employer agrees to let you work from home, your perceived value is high enough that satisfying you with money only would be painful. But as you spend more time at home, they start noticing your value less, which leads to the whole "people are more productive at the office" mentality.
