We all get asked this question and we all ask it - here in the States, at least. They don’t really ask the “what do you do” question in other countries.
We Americans ask it almost immediately upon meeting someone.
We use it as our way of getting to know more about that person, but we - subconsciously, maybe - also use it to make a decision. We decide what we think of the other person based on what they do for a living, placing them on an invisible but very present ladder of sorts.
“I’m a used car salesman.” Ok, we’ll put him down here, about midway down.
“I own a flooring company.” Got it - ok, we’re sticking you higher up there where business owners go.
“I’m a stay-at-home mom.” So - nothing. Doesn’t even make it on the ladder.
Sucks that stay-at-home-moms don’t get on the ladder, much less get their rightful spot at the very top of it.
