This is true up until a point, and then the pattern starts to reverse. Like, the receptionist isn't going to get 2 monitors. They're likely to get one monitor and a very old desktop, or an old laptop.

Edit: Also an intern / co-op student / work experience student, etc. is probably as low as you can go on the totem pole of office work. I bet in many cases they're not even assigned a permanent office / cubicle since they're expected to shadow / be mentored by a variety of people. As a result, they probably get a second-hand, used laptop.

And, if the company has retail sales, techs who do installations, etc. they're often very low on the totem pole, and they're often not getting a computer at all. Maybe in some cases they'd get a "work phone", so they'd have the same kind of equipment as the CEO, but effectively be at the opposite end of the pole from them.
