"Pantry" being a metaphor for whatever you have stored away, not a physical room. Regardless of your income unless it is extremely low or you are unemployed, whether or not you live paycheck to paycheck is a function of your decisions, not of your income. You will, in fact, have a considerably larger amount of money to spend, if you don't waste it on small volume frequent purchases.

There simply would’ve been no place to put bulk toilet paper in my 600/700 sq foot one bedroom in Seattle. Lots of people live in even smaller spaces.

I’ve lived this small and you get clever. I put things in storage under my bed, in my bookshelf, and in boxes in my closet. Worst case, I would just stack them in the open or on counters, behind the sink, and on window ledges

Whether or not you have a purpose built pantry is mostly just a reflection of the age of the building you live in.

A lot of bottom dollar apartments wind up having unintentional pantries because they wind up dividing a floor of an existing building in such a way that you wind up with a closet in the kitchen.
