if elevators or escalators hadn't been invented do you think CEO and owners would have their offices on the ground floor and make everyone work up

That's where Otis came in. Look it up

They'd run stairs on your mom.

Sherlock, do you think that if elevators hadn't been invented that the technology would have existed to build structures of 40 floors?

No. They would have people carry them up stairs, or hoist them using manual elevator systems. The status symbol would be in having the people putting in labor to elevate them.

The way many have drivers instead of driving themselves.

Ropes where used for thousands of years. That was the most basic elevator. Even monkeys use vines.

They’d have used dumbwaiters

people would be too tired
