Yes, this doesn't add up. The typical 2x20 mins daily commute is effectively an 8% unpaid increase in working hours, not counting transportation costs.
I don't know anyone with a 20 minute commute- I'd be in the office every day if I had that. Actually I think the commute pain is the best single predictor of how people feel about going back to the office.
While people driving cars solo is surely a pitiable waste of time and resources, and my current commute is about 20ft from bedroom to living room, I would say that a happy medium has been my public transit-based commutes.
As long as there's at least one leg with a long-haul distance (30+ minutes), I am usually able to enter a calm and meditative state, lower my blood pressure, and set aside the cares of home and work alike. This is not always the case, because there may be stressors from other passengers, but most of the time, my situational awareness does not require rapt attention, and I can soften my gaze, stare out the window, or poke my nose into my phone.
It is often difficult to describe to recruiters how public transit makes my commute different, not just more time. The distance calculations work differently: based on number of transfer points and frequency of service, etc.
You can also sit out on your porch or deck in the morning before work with a cup of coffee and a podcast, and meditate, relax, or whatever you like to do to get ready for work.
I've heard managers try to spin a commute as a good thing, giving you transition time between work and home, but it always comes off to me as corporate BS and nothing you can't also do at home without dealing with traffic or public transit.
Part of my imperfect joy in commuting to work in an office is neither being at home, nor at work, for a while. That's my POV. Sit on your porch if you want. I love the train. I have this in common with Iggy Pop and Siouxsie:
There isn't anything to add. They surveyed people and found that people dislike switching from having a flexible schedule to a traditional one as much as experiencing a 2-3% pay cut. Through I agree, if most people did do a bit of math they would realize they should be significantly more upset.
