The career-related reasons why early-career employees want to go in to office are valid. But that is not the whole story.
For many early-career engineers living away from families in cities like SF, Seattle etc have better office spaces than personal living spaces - better buildings, better air conditioning, better TV, better restrooms, better kitchens, better stocked fridges etc. This factor does not apply as much to later-career employees who live in the suburbs.
