Phone booths are made by the phone company to increase the money they make, that's political. Phone booths are made with more or less shielding implying a greater or lesser danger to their occupant, that's politics. The ones at the airport have glass dividers while the ones at the lonely gas station at night are fully enclosed with thick glass. Different ones have different amounts of graffiti and different likelihood of being vandalised at any given time. You will find this correlates with demographics. Phone booths have disappeared as we all got portable phones in our pockets, but those phones also track us and some people might prefer the relative privacy of an impersonal phone booth, but can't because they no longer exist.
