working in office culture = more people in his city spending money day to day + more offices needed because workers are expected to be there + more property value from more property demand due to return to office culture.
Mayors of cities have a vested interest in having full office buildings which provide more funding to the city through worker/poor tax (sales tax) instead of corporate tax hikes.
If the ownership class stands to benefit from the status quo continuing they will 100% impose the status quo.
