Some items absolutely are zero sum - anything that is in short supply with a high demand becomes unobtainable for anyone who isn't rich.
Some things that are effectively out of reach for at least half of everyone:
Mansions and Luxury Condos in desirable locations
Private Jet
Private Island
The best quality food
2021 Ferrari 812 GTS
The best legal advice
A favor from a US Senator
These things are effectively zero-sum, only a limited number of people can have them and we can't expand the supply very much (or intentionally don't because that would hurt their exclusivity value).
