Everyone carries a mix of resources, what Bourdieu calls capital: money (economic), know-how and taste (cultural), useful connections (social), and recognised prestige (symbolic). The two people below carry very different mixes of it. Send each of them into a social setting, a "field", and watch how much standing they command there. Their resources never change from one setting to the next. The only thing that changes is the room they walk into.
Drop them into a field
Same two people, the same resources, opposite standing, and the only thing that changed was the field. That is Bourdieu's point: each arena is its own "field" with its own currency, and the capital that makes you powerful in one can be near-worthless in another (Bourdieu, 1986). Money dominates the pitch and barely registers at the gallery; credentials rule the committee and buy nothing in the club.
Capital also does not convert freely across fields, which is why prestige earned in one world so often fails to transfer to another. The practical move is to work out which capital a field actually rewards before you spend the wrong one, and to notice when your own sense of "obvious standing" is really just the currency of the field you happen to come from.
