Yea to those that don't get it, "boomer" isn't necessarily the baby boomer generation it's just how younger people refer to older people these days.
The idea that we are supposed to drive in traffic and sit in a cubicle for 10 hours a day, 5 days a week, is a "boomer" concept, because only boomers were alive when that was a viable deal.
Back then remote work wasn't an option, back then America actually produced things, back then you could afford a house and support a family off one salary and didn't have to compete with a billion Indians and insane inflation.
Boomers tend to be slower workers also, I've noticed something that takes a younger worker 30 minutes to do can take a boomer 2 hours or more. Boomers cope with this fact by pretending it isn't efficiency that matters, but how long you sit in a cubicle. They pretend that the younger worker who finished the task in 1 hour then left is "lazy" and they are a "hard worker" because they took 10 hours to do it.
Many boomers also have miserable domestic situations (that generation is when divorce rates exploded). Many are so miserable at home they would rather stay in the office to avoid their spouse... which is fine, but then they push for RTO and pretend its about other stuff like "collaboration".
So yes RTO is essentially a "boomer" concept resulting from old people trying to make younger people as miserable as they are.
